4 ! a screen saver and locker for the X window system
10 ! See "man xscreensaver" for more info. The latest version is always
11 ! available at http://www.jwz.org/xscreensaver/
14 ! These resources, when placed in the system-wide app-defaults directory
15 ! (e.g., /usr/lib/X11/app-defaults/XScreenSaver) will provide the default
16 ! settings for new users. However, if you have a ".xscreensaver" file in
17 ! your home directory, the settings in that file take precedence.
20 ! Don't hand this file to "xrdb" -- that isn't how app-defaults files work.
21 ! Though app-defaults files have (mostly) the same syntax as your ~/.Xdefaults
22 ! file, they are used differently, and if you run this file through xrdb,
23 ! you will probably mess things up.
25 #error Do not run app-defaults files through xrdb!
26 #error That does not do what you might expect.
27 #error Put this file in /usr/lib/X11/app-defaults/XScreenSaver instead.

93 ! Turning on "installColormap" interacts erratically with twm and tvtwm,
94 ! but seems to work fine with mwm and olwm. Try it and see. If your
95 ! screen turns some color other than black, the window manager is buggy,
96 ! and you need to set this resource to False (or get a WM that works.)
98 *installColormap: True
101 ! Any program which can draw on the root window will work as a screensaver.
102 ! The following resource enumerates them.
104 ! Programs are separated by newlines (specified in resource files with \n).
105 ! Lines may be continued with a lone \ at the end of the line.
107 ! Each line is an `sh' command.
109 ! If the first (non-blank) character on the line is "-", then that means
110 ! that this command is disabled: it's still in the list, but it won't ever
111 ! be used. (This is just to make it easy to disable and then re-enable
114 ! If the first word on the line is the name of a visual followed by a
115 ! colon, then that visual will be used for the program, if it is available.
116 ! If no such visual is available, then the program will be skipped. In
117 ! this way, you can specify that you want certain programs to run only
118 ! on color screens, and others only on mono screens, by making use of the
119 ! magic visual names "color" and "mono". Likewise, if some hacks prefer
120 ! colormaps, but others prefer 24-bit windows, that also can be arranged
121 ! (in this case, by using "PseudoColor:" versus "TrueColor:".)
123 ! Some of the screenhacks are written using OpenGL. OpenGL programs are
124 ! a bit different than normal X programs, in that they prefer visuals that
125 ! are *half* as deep as the screen. You can tell xscreensaver to select a
126 ! good visual for a GL program by using the magic visual name "GL".
128 ! All programs must be launched in such a way that they draw on the root
129 ! window; they should not be spawned in the background with "&". If shell
130 ! metacharacters are used, they must be understandable to `sh', not `csh'
131 ! (the $SHELL variable is not consulted, for unfortunate but good reasons.)
133 ! Be sure to check out Demo Mode: run the `xscreensaver-demo' program to
134 ! edit the current list of programs interactively, try out the various modes,
135 ! and change other parameters. See the man page for details.

320 ! default-n: "Slideshow" xv -root -rmode 5 -random -viewonly \
321 ! -wloop -wait 30 $HOME/bitmaps/*.jpg \n\
323 ! or, if you prefer "xli" to "xv", like this: (but note that xli's "-delay"
324 ! option doesn't work in conjunction with "-onroot", so you need to add a
325 ! line for each image individually... "xv" is better in this respect.)

330 ! $HOME/bitmaps/pic2.jpg \n\
331 ! default-n: xli -quiet -onroot -center -border black \
332 ! $HOME/bitmaps/pic3.jpg \n\
334 ! Note that we've used "default-n" as the visual name, rather than just
335 ! "default": this means "default visual, no install", that is, it's like
336 ! specifying the command-line arguments "-visual default -no-install".
337 ! This is necessary because, when XV or XLI arerunning in "-root" mode, they
338 ! always assume that the default visual and colormap are being used, rather
339 ! than examining the window it is drawing on to see what visual and colormap
340 ! it has. If we didn't force the default visual to be used, we would get an
341 ! X error. If we didn't force the default colormap to be installed, the
342 ! colors would be all wrong. "default-i" may also be used as a visual name
343 ! (meaning, "-visual default -install") but you probably won't ever need
347 ! Some of the GL demos that SGI ships work with XScreenSaver; most don't.
348 ! XScreenSaver includes a program (not built or installed by default)
349 ! called "xscreensaver-sgigl". To use the SGI demos with XScreenSaver,
350 ! build that program, and use it to launch the SGI demos. For example,
351 ! on Irix 6.2, you can do this:
353 ! xscreensaver-sgigl /usr/demos/bin/ep -S
354 ! xscreensaver-sgigl /usr/demos/bin/bongo
356 ! On Irix 6.3, things have moved, so you need to do it like this:
358 ! xscreensaver-sgigl /usr/sbin/ep -S
360 ! (But note that, on non-SGIs, the bundled "stonerview" hack is a decent
361 ! clone of "ep". Yay!)
363 ! You can also use the "ant" demo, but first you need to wrap a shell script
364 ! around it that cds to its home directory, so that it can find its files;
365 ! and also pass it the -S argument, to prevent it from forking. What a mess!
366 ! Basically, the SGI demo writers went out of their way to make my life hell.

559 *hacks.documentation.isInstalled: True
561 *hacks.qix.documentation: \
562 This is the swiss army chainsaw of qix programs. It bounces a series \
563 of line segments around the screen, and uses variations on this basic \
564 motion pattern to produce all sorts of different presentations: line \
565 segments, filled polygons, overlapping translucent areas... Written \
568 *hacks.attraction.documentation: \
569 Like qix, this uses a simple simple motion model to generate many \
570 different display modes. The control points attract each other up to \
571 a certain distance, and then begin to repel each other. The \
572 attraction/repulsion is proportional to the distance between any two \
573 particles, similar to the strong and weak nuclear forces. \
575 One of the most interesting ways to watch this hack is simply as \
576 bouncing balls, because their motions and interactions with each \
577 other are so odd. Sometimes two balls will get into a tight orbit \
578 around each other, to be interrupted later by a third, or by the edge \
579 of the screen. It looks quite chaotic. \
581 Written by Jamie Zawinski, based on Lisp code by John Pezaris.
583 *hacks.pyro.documentation: \
584 Pyro draws exploding fireworks. Blah blah blah. Written by Jamie \
587 *hacks.helix.documentation: \
588 This repeatedly generates spirally string-art-ish patterns. Written \
591 *hacks.pedal.documentation: \
592 This is sort of a combination spirograph/string-art. It generates a \
593 large, complex polygon, and lets the X server do the bulk of the work \
594 by giving it an even/odd winding rule. Written by Dale Moore, based \
595 on some ancient PDP-11 code.
597 *hacks.rorschach.documentation: \
598 This generates random inkblot patterns. The algorithm is deceptively \
599 simple for how well it works; it merely walks a dot around the screen \
600 randomly, and then reflects the image horizontally, vertically, or \
601 both. Any deep-seated neurotic tendencies which this program reveals \
602 are your own problem. Written by Jamie Zawinski.
604 *hacks.hopalong.documentation: \
605 This draws lacy fractal patterns, based on iteration in the imaginary \
606 plane, from a 1986 Scientific American article. Mostly written by \
609 *hacks.greynetic.documentation: \
610 This draws random colored and stippled rectangles. Written by Jamie \
613 *hacks.imsmap.name: IMSmap
614 *hacks.imsmap.documentation: \
615 This generates random cloud-like patterns. It looks quite different \
616 in monochrome and color. The basic idea is to take four points on \
617 the edge of the image, and assign each a random ``elevation''. Then \
618 find the point between them, and give it a value which is the average \
619 of the other four, plus some small random offset. Then coloration is \
620 done based on elevation. \
622 The color selection is done by binding the elevation to either hue, \
623 saturation, or brightness, and assigning random values to the others. \
624 The ``brightness'' mode tends to yield cloudlike patterns, and the \
625 others tend to generate images that look like heat-maps or CAT-scans. \
626 Written by Juergen Nickelsen and Jamie Zawinski.
628 *hacks.slidescreen.name: SlideScreen
629 *hacks.slidescreen.documentation: \
630 This grabs an image of whatever is on your screen, divides it into a \
631 grid, and then randomly shuffles the squares around as if it was one \
632 of those annoying ``16-puzzle'' games, where there is a grid of \
633 squares, one of which is missing. I hate trying to solve those \
634 puzzles, but watching one permute itself is more amusing. Written by \
637 *hacks.decayscreen.name: DecayScreen
638 *hacks.decayscreen.documentation: \
639 This grabs an image of whatever is on your screen, and makes it melt. \
640 You've no doubt seen this effect before, but no screensaver would \
641 really be complete without it. It works best if there's something \
642 colorful visible. Warning, if the effect continues after the screen \
643 saver is off, seek medical attention. Written by David Wald and \
646 A number of these screenhacks have the ability to take an image of \
647 your desktop and manipulate it in some way. On SGI systems, these \
648 programs are able to (at random) pull their source image from the \
649 system's video input instead! This works nicely if you leave some \
650 some random television station plugged in.
652 *hacks.jigsaw.documentation: \
653 This grabs a screen image, carves it up into a jigsaw puzzle, \
654 shuffles it, and then solves the puzzle. This works especially well \
655 when you feed it an external video signal instead of letting it grab \
656 the screen image (actually, I guess this is generally true...) When \
657 it is grabbing a video image, it is sometimes pretty hard to guess \
658 what the image is going to look like once the puzzle is solved. \
659 Written by Jamie Zawinski.
661 *hacks.blitspin.name: BlitSpin
662 *hacks.blitspin.documentation: \
663 The ``blitspin'' hack repeatedly rotates a bitmap by 90 degrees by \
664 using logical operations: the bitmap is divided into quadrants, and \
665 the quadrants are shifted clockwise. Then the same thing is done \
666 again with progressively smaller quadrants, except that all \
667 sub-quadrants of a given size are rotated in parallel. Written by \
668 Jamie Zawinski based on some cool SmallTalk code seen in in Byte \
671 As you watch it, the image appears to dissolve into static and then \
672 reconstitute itself, but rotated. You can provide the image to use, \
673 as an XBM or XPM file, or tell it to grab a screen image and rotate \
676 *hacks.slip.documentation: \
677 This program throws some random bits on the screen, then sucks them \
678 through a jet engine and spews them out the other side. To avoid \
679 turning the image completely to mush, every now and then it will and \
680 then it interjects some splashes of color into the scene, or go into \
681 a spin cycle, or stretch the image like taffy, or (this is my \
682 addition) grab an image of your current desktop to chew on. \
683 Originally written by Scott Draves; whacked on by Jamie Zawinski.
685 *hacks.distort.documentation: \
686 This hack grabs an image of the screen, and then lets a transparent \
687 lens wander around the screen, magnifying whatever is underneath. \
688 Written by Jonas Munsin.
690 *hacks.spotlight.documentation: \
691 Draws a spotlight scanning across a black screen, illumnating the \
692 underlying desktop when it passes. Written by Rick Schultz.
694 *hacks.hypercube.documentation: \
695 This displays 2D projections of the sequence of 3D objects which are \
696 the projections of the 4D analog to the cube: as a square is composed \
697 of four lines, each touching two others; and a cube is composed of \
698 six squares, each touching four others; a hypercube is composed of \
699 eight cubes, each touching six others. To make it easier to \
700 visualize the rotation, it uses a different color for the edges of \
701 each face. Don't think about it too long, or your brain will melt. \
702 Written by Joe Keane, Fritz Mueller, and Jamie Zawinski.
704 *hacks.hyperball.documentation: \
705 Hyperball is to hypercube as dodecahedron is to cube: this displays \
706 a 2D projection of the sequence of 3D objects which are the projections \
707 of the 4D analog to the dodecahedron. Written by Joe Keane.
709 *hacks.halo.documentation: \
710 This draws trippy psychedelic circular patterns that hurt to look at. \
711 It can also animate the control-points, but that takes a lot of CPU \
712 and bandwidth. Written by Jamie Zawinski.
714 *hacks.maze.documentation: \
715 This is the ancient X maze demo, modified to work with xscreensaver. \
716 It generates a random maze, then solves it with visual feedback. \
717 Originally by Jim Randell; modified by a cast of thousands.
719 *hacks.noseguy.documentation: \
720 A little man with a big nose wanders around your screen saying \
721 things. The things which he says can come from a file, or from an \
722 external program like `zippy' or `fortune'. This was extracted from \
723 `xnlock' by Dan Heller. Colorized by Jamie Zawinski.
725 *hacks.flame.documentation: \
726 Another iterative fractal generator. Written by Scott Draves.
728 *hacks.lmorph.name: LMorph
729 *hacks.lmorph.documentation: \
730 This generates random spline-ish line drawings and morphs between \
731 them. Written by Sverre H. Huseby and Glenn T. Lines.
733 *hacks.deco.documentation: \
734 This one subdivides and colors rectangles randomly. It looks kind of \
735 like Brady-Bunch-era rec-room wall paneling. (Raven says: ``this \
736 screensaver is ugly enough to peel paint.'') Written by Jamie \
737 Zawinski, inspired by Java code by Michael Bayne.
739 *hacks.moire.documentation: \
740 This one draws cool circular interference patterns. Most of the \
741 circles you see aren't explicitly rendered, but show up as a result \
742 of interactions between the other pixels that were drawn. Written by \
743 Jamie Zawinski, inspired by Java code by Michael Bayne. As he \
744 pointed out, the beauty of this one is that the heart of the display \
745 algorithm can be expressed with just a pair of loops and a handful of \
746 arithmetic, giving it a high ``display hack metric''.
748 *hacks.moire2.documentation: \
749 Another example of the fun you can have with moire \
750 interference patterns; this hack generates fields of concentric \
751 circles or ovals, and combines the planes with various operations. \
752 The planes are moving independently of one another, causing the \
753 interference lines to ``spray.'' Written by Jamie Zawinski.
755 *hacks.lightning.documentation: \
756 This one draws crackling fractal lightning bolts. It's simple, \
757 direct, and to the point. If only it had sound... Written by Keith \
760 *hacks.strange.documentation: \
761 This draws strange attractors: it's a colorful, \
762 unpredictably-animating field of dots that swoops and twists around. \
763 The motion is very nice. Written by Massimino Pascal.
765 *hacks.spiral.documentation: \
766 Moving circular patterns, by Peter Schmitzberger. Moving circular \
767 patterns means moire; interference patterns, of course.
769 *hacks.laser.documentation: \
770 Moving radiating lines, that look vaguely like scanning laser beams. \
771 Written by Pascal Pensa. (Frankie say: relax.)
773 *hacks.grav.documentation: \
774 This program draws a simple orbital simulation. If you turn on \
775 trails, it looks kind of like a cloud-chamber photograph. Written \
778 *hacks.drift.documentation: \
779 How could one possibly describe this except as ``drifting recursive \
780 fractal cosmic flames?'' Another fine hack from the Scott Draves \
781 collection of fine hacks.
784 *hacks.ifs.documentation: \
785 This one draws spinning, colliding iterated-function-system images. \
786 Written by Massimino Pascal.
788 *hacks.julia.documentation: \
789 This one draws spinning, animating (are you detecting a pattern here \
790 yet?) explorations of the Julia set. You've probably seen static \
791 images of this fractal form before, but it's a lot of fun to watch in \
792 motion as well. One interesting thing is that there is a small \
793 swinging dot passing in front of the image, which indicates the \
794 control point from which the rest of the image was generated. \
795 Written by Sean McCullough.
797 *hacks.penrose.documentation: \
798 Draws quasiperiodic tilings; think of the implications on modern \
799 formica technology. Written by Timo Korvola. \
801 In April 1997, Sir Roger Penrose, a British math professor who has \
802 worked with Stephen Hawking on such topics as relativity, black \
803 holes, and whether time has a beginning, filed a \
804 copyright-infringement lawsuit against the Kimberly-Clark \
805 Corporation, which Penrose said copied a pattern he created (a \
806 pattern demonstrating that ``a nonrepeating pattern could exist in \
807 nature'') for its Kleenex quilted toilet paper. Penrose said he \
808 doesn't like litigation but, ``When it comes to the population of \
809 Great Britain being invited by a multinational to wipe their bottoms \
810 on what appears to be the work of a Knight of the Realm, then a last \
811 stand must be taken.'' \
813 As reported by News of the Weird #491, 4-jul-1997.
815 *hacks.sierpinski.documentation: \
816 This draws the two-dimensional variant of the recursive Sierpinski \
817 triangle fractal. Written by Desmond Daignault.
819 *hacks.braid.documentation: \
820 Draws random color-cycling inter-braided concentric circles. Written \
823 *hacks.galaxy.documentation: \
824 This draws spinning galaxies, which then collide and scatter their \
825 stars to the, uh, four winds or something. Originally an Amiga \
826 program by Uli Siegmund.
828 *hacks.bouboule.documentation: \
829 This draws what looks like a spinning, deforming baloon with \
830 varying-sized spots painted on its invisible surface. Written by \
833 *hacks.swirl.documentation: \
834 More flowing, swirly patterns. This version is by M. Dobie and R. \
835 Taylor, but you might have seen a Mac program similar to this called \
836 FlowFazer. There is also a cool Java applet of a similar concept
838 *hacks.flag.documentation: \
839 This draws a waving colored flag, that undulates its way around the \
840 screen. The trick is the flag can contain arbitrary text and images. \
841 By default, it displays either the current system name and OS \
842 type, or a picture of ``Bob,'' but you can replace the text or the \
843 image with a command-line option. Written by Charles Vidal and Jamie \
846 *hacks.sphere.documentation: \
847 Another of the classic screenhacks of the distant past, this one \
848 draws shaded spheres in multiple colors. This hack traces its \
849 lineage back to Tom Duff in 1982.
851 *hacks.forest.documentation: \
852 This draws fractal trees. Written by Peter Baumung. Everybody loves \
855 *hacks.lisa.documentation: \
856 This draws Lisajous loops, by Caleb Cullen. Remember that device \
857 they had the Phantom Zone prisoners in during their trial in \
858 Superman? I think that was one of these.
860 *hacks.lissie.documentation: \
861 Another Lissajous figure. This one draws the progress of circular \
862 shapes along a path. Written by Alexander Jolk.
864 *hacks.goop.documentation: \
865 This draws set of animating, transparent, amoeba-like blobs. The \
866 blobs change shape as they wander around the screen, and they are \
867 translucent, so you can see the lower blobs through the higher ones, \
868 and when one passes over another, their colors merge. Written by \
869 Jamie Zawinski. I got the idea for this from a cool mouse pad I \
870 have, which achieves the same kind of effect in real life by having \
871 several layers plastic with colored oil between them. Written by \
874 *hacks.starfish.documentation: \
875 This generates a sequence of undulating, throbbing, star-like \
876 patterns which pulsate, rotate, and turn inside out. Another display \
877 mode uses these shapes to lay down a field of colors, which are then \
878 cycled. The motion is very organic. Written by Jamie Zawinski.
880 *hacks.munch.documentation: \n\
887 As reported by HAKMEM, in 1962, Jackson Wright wrote the above PDP-1 \
888 code. That code still lives on in this screenhack, some 35 years \
889 later. The number of lines of enclosing code has increased \
890 substantially, however. This version is by Tim Showalter.
892 *hacks.fadeplot.name: FadePlot
893 *hacks.fadeplot.documentation: \
894 Draws what looks like a waving ribbon following a sinusoidal path. \
895 Written by Bas van Gaalen and Charles Vidal.
897 *hacks.coral.documentation: \
898 Simulates coral growth, albeit somewhat slowly. This image doesn't \
899 really do it justice. Written by Frederick Roeber.
901 *hacks.mountain.documentation: \
902 Generates random 3d plots that look vaguely mountainous. Written by \
905 *hacks.triangle.documentation: \
906 Generates random mountain ranges using iterative subdivision of \
907 triangles. Written by Tobias Gloth.
909 *hacks.worm.documentation: \
910 An ancient xlock hack that draws multicolored worms that crawl around \
911 the screen. Written by Brad Taylor, Dave Lemke, Boris Putanec, and \
914 *hacks.rotor.documentation: \
915 Another ancient xlock demo, this one by Tom Lawrence. It draws a \
916 line segment moving along a complex spiraling curve. I tweaked this \
917 to generate curvier lines, but still frames of it don't look like \
920 *hacks.ant.documentation: \
921 A cellular automaton that is really a two-dimensional Turing machine: \
922 as the heads (``ants'') walk along the screen, they change pixel \
923 values in their path. Then, as they pass over changed pixels, their \
924 behavior is influenced. Written by David Bagley.
926 *hacks.demon.documentation: \
927 A cellular automaton that starts with a random field, and organizes \
928 it into stripes and spirals. Written by David Bagley.
930 *hacks.loop.documentation: \
931 This one produces loop-shaped colonies that spawn, age, and \
932 eventually die. Written by David Bagley.
934 *hacks.vines.documentation: \
935 This one generates a continuous sequence of small, curvy geometric \
936 patterns. It scatters them around your screen until it fills up, \
937 then it clears the screen and starts over. Written by Tracy Camp and \
940 *hacks.kaleidescope.documentation: \
941 Another clone of an ancient meme, consisting largely of frenetic \
942 rotational motion of colored lines. This one is by Ron Tapia. The \
943 motion is nice, but I think it needs more solids, or perhaps just \
944 brighter colors. More variations in the rotational speed might help, \
947 *hacks.xjack.documentation: \
948 This program behaves schizophrenically and makes a lot of typos. \
949 Written by Jamie Zawinski. If you haven't seen Stanley Kubrick's \
950 masterpiece, ``The Shining,'' you won't get it. Those who have \
951 describe this hack as ``inspired.''
953 *hacks.xlyap.documentation: \
954 This generates pretty fractal pictures by doing funky math involving \
955 the ``Lyapunov exponent.'' It has a cool interactive mode, too. \
956 Written by Ron Record.
958 *hacks.cynosure.documentation: \
959 A hack similar to `greynetic', but less frenetic. The first \
960 implementation was by Stephen Linhart; then Ozymandias G. Desiderata \
961 wrote a Java applet clone. That clone was discovered by Jamie \
962 Zawinski, and ported to C for inclusion here.
964 *hacks.flow.documentation: \
965 Another series of strange attractors: a flowing series of points, \
966 making strange rotational shapes. Written by Jeff Butterworth.
968 *hacks.epicycle.documentation: \
969 This program draws the path traced out by a point on the edge of a \
970 circle. That circle rotates around a point on the rim of another \
971 circle, and so on, several times. These were the basis for the \
972 pre-heliocentric model of planetary motion. Written by James \
975 *hacks.interference.documentation: \
976 Another color-field hack, this one works by computing decaying \
977 sinusoidal waves, and allowing them to interfere with each other as \
978 their origins move. Written by Hannu Mallat.
980 *hacks.truchet.documentation: \
981 This draws line- and arc-based Truchet patterns that tile the screen. \
982 Written by Adrian Likins.
984 *hacks.bsod.name: BSOD
985 *hacks.bsod.documentation: \
986 BSOD stands for ``Blue Screen of Death.'' The finest in personal \
987 computer emulation, this hack simulates popular screen savers from a \
988 number of less robust operating systems. Written by Jamie Zawinski.
990 *hacks.crystal.documentation: \
991 Moving polygons, similar to a kaleidescope (more like a kaleidescope \
992 than the hack called `kaleid,' actually.) This one by Jouk Jansen.
994 *hacks.discrete.documentation: \
995 More ``discrete map'' systems, including new variants of Hopalong and \
996 Julia, and a few others. Written by Tim Auckland.
998 *hacks.kumppa.documentation: \
999 Spiraling, spinning, and very, very fast splashes of color rush \
1000 toward the screen. Written by Teemu Suutari.
1002 *hacks.rd-bomb.name: RD-Bomb
1003 *hacks.rd-bomb.documentation: \
1004 Another variation of the `Bomb' program by Scott Draves. This draws \
1005 a grid of growing square-like shapes that, once they overtake each \
1006 other, react in unpredictable ways. ``RD'' stands for \
1009 *hacks.sonar.documentation: \
1010 This program draws a simulation of a sonar screen. Written by \
1011 default, it displays a random assortment of ``bogies'' on the screen, \
1012 but if compiled properly, it can ping (pun intended) your local \
1013 network, and actually plot the proximity of the other hosts on your \
1014 network to you. It would be easy to make it monitor other sources of \
1015 data, too. (Processes? Active network connections? CPU usage per \
1016 user?) Written by Stephen Martin.
1018 *hacks.t3d.name: T3D
1019 *hacks.t3d.documentation: \
1020 This draws a working analog clock composed of floating, throbbing \
1021 bubbles. Written by Bernd Paysan.
1023 *hacks.penetrate.documentation: \
1024 This hack simulates the classic arcade game Missile Command. Written \
1027 *hacks.deluxe.documentation: \
1028 This draws a pulsing sequence of stars, circles, and lines. It would \
1029 look better if it was faster, but as far as I can tell, there is no \
1030 way to make this be both: fast, and flicker-free. Yet another reason \
1031 X sucks. Written by Jamie Zawinski.
1033 *hacks.compass.documentation: \
1034 This draws a compass, with all elements spinning about randomly, for \
1035 that ``lost and nauseous'' feeling. Written by Jamie Zawinski.
1037 *hacks.squiral.documentation: \
1038 Draws a set of interacting, square-spiral-producing automata. The \
1039 spirals grow outward until they hit something, then they go around \
1040 it. Written by Jeff Epler.
1042 *hacks.xflame.documentation: \
1043 Draws a simulation of pulsing fire. It can also take an arbitrary \
1044 image and set it on fire too. Written by Carsten Haitzler, hacked on \
1047 *hacks.wander.documentation: \
1048 Draws a colorful random-walk, in various forms. Written by Rick \
1051 *hacks.critical.documentation: \
1052 Draws a system of self-organizing lines. It starts out as random \
1053 squiggles, but after a few iterations, order begins to appear. \
1054 Written by Martin Pool.
1056 *hacks.phosphor.documentation: \
1057 Draws a simulation of an old terminal, with large pixels and \
1058 long-sustain phosphor. It can run any program as a source of the text \
1059 it displays. Written by Jamie Zawinski.
1061 *hacks.xmatrix.documentation: \
1062 A rendition of the text scrolls seen in the movie ``The Matrix.'' \
1063 Written by Jamie Zawinski.
1065 *hacks.petri.documentation: \
1066 This simulates colonies of mold growing in a petri dish. Growing \
1067 colored circles overlap and leave spiral interference in their wake. \
1068 Written by Dan Bornstein.
1070 *hacks.shadebobs.name: ShadeBobs
1071 *hacks.shadebobs.documentation: \
1072 This draws smoothly-shaded oscilating oval patterns, that look \
1073 something like vapor trails or neon tubes. Written by Shane Smit.
1075 *hacks.ccurve.name: C Curve
1076 *hacks.ccurve.documentation: \
1077 Generates self-similar linear fractals, including the classic ``C \
1078 Curve.'' Written by Rick Campbell.
1080 *hacks.blaster.documentation: \
1081 Draws a simulation of flying space-combat robots (cleverly disguised \
1082 as colored circles) doing battle in front of a moving star field. \
1083 Written by Jonathan Lin.
1085 *hacks.bumps.documentation: \
1086 A bit like `Spotlight', except that instead of merely exposing part \
1087 of your desktop, it creates a bump map from it. Basically, it \
1088 3D-izes a roaming section of your desktop, based on color intensity. \
1089 Written by Shane Smit.
1091 *hacks.xteevee.name: XTeeVee
1092 *hacks.xteevee.documentation: \
1093 XTeeVee simulates various television problems, including static, \
1094 loss of vertical hold, and a test pattern. By Greg Knauss.
1096 *hacks.xspirograph.name: XSpiroGraph
1097 *hacks.xspirograph.documentation: \
1098 Simulates that pen-in-nested-plastic-gears toy from your childhood. \
1101 *hacks.nerverot.name: NerveRot
1102 *hacks.nerverot.documentation: \
1103 Draws different shapes composed of nervously vibrating squiggles, \
1104 as if seen through a camera operated by a monkey on crack. \
1107 *hacks.webcollage.name: WebCollage
1108 *hacks.webcollage.documentation: \
1109 This program makes collages out of random images pulled off of the \
1110 World Wide Web. It finds these images by doing random web searches, \
1111 and then extracting images from the returned pages. It can also be \
1112 set up to filter the images through the `VidWhacker' program, above, \
1113 which looks really great. \
1115 (Note that most of the images it finds are text, and not pictures. \
1116 This is because most of the web is pictures of text. Which is pretty \
1117 sad.) Written by Jamie Zawinski.
1119 *hacks.vidwhacker.name: VidWhacker
1120 *hacks.vidwhacker.documentation: \
1121 This is actually just a shell script that grabs a frame of video from \
1122 the system's video input, and then uses some PBM filters (chosen at \
1123 random) to manipulate and recombine the video frame in various ways \
1124 (edge detection, subtracting the image from a rotated version of \
1125 itself, etc.) Then it displays that image for a few seconds, and \
1126 does it again. This works really well if you just feed broadcast \
1127 television into it. \
1129 Currently, the three lines of the script that actually grab the \
1130 source picture are SGI specific, but it should be trivial to adapt it \
1131 to work on other systems that can grab video (please send me the \
1132 changes if you do this...)
1134 *hacks.rocks.documentation: \
1135 This draws an animation of flight through an asteroid field, with \
1136 changes in rotation and direction. It can also display 3D \
1137 separations for red/blue glasses! Mostly written by Jamie Zawinski.
1139 *hacks.bubbles.documentation: \
1140 This simulates the kind of bubble formation that happens when water \
1141 boils:small bubbles appear, and as they get closer to each other, \
1142 they combine to form larger bubbles, which eventually pop. Written \
1145 *hacks.gears.documentation: \
1146 This draws sets of turning, interlocking gears, rotating in three \
1147 dimensions. Another GL hack, by Danny Sung, Brian Paul, Ed Mackey, \
1150 *hacks.superquadrics.documentation: \
1151 Ed Mackey reports that he wrote the first version of this program in \
1152 BASIC on a Commodore 64 in 1987, as a 320x200 black and white \
1153 wireframe. Now it is GL and has specular reflections.
1155 *hacks.morph3d.name: Morph3D
1156 *hacks.morph3d.documentation: \
1157 Another 3d shape-changing GL hack, by Marcelo Vianna. It has the \
1158 same shiny-plastic feel as Superquadrics, as many computer-generated \
1161 *hacks.cage.documentation: \
1162 This draws Escher's ``Impossible Cage,'' a 3d analog of a moebius \
1163 strip, and rotates it in three dimensions. Written by Marcelo \
1166 *hacks.moebius.documentation: \
1167 Another M. C. Escher hack by Marcelo Vianna, this one draws \
1168 ``Moebius Strip II,'' a GL image of ants walking along the surface of \
1171 *hacks.stairs.documentation: \
1172 by Marcelo Vianna's third Escher GL hack, this one draws an \
1173 ``infinite'' staircase.
1175 *hacks.pipes.documentation: \
1176 If you've ever been in the same room with a Windows NT machine, \
1177 you've probably seen this GL hack. This version is by Marcelo \
1180 *hacks.sproingies.documentation: \
1181 Q-Bert meets Marble Madness! Written by Ed Mackey.
1183 *hacks.rubik.documentation: \
1184 Draws a Rubik's Cube that rotates in three dimensions and repeatedly \
1185 shuffles and solves itself. Another fine GL hack by Marcelo Vianna.
1187 *hacks.atlantis.documentation: \
1188 This is xfishtank writ large: a GL animation of a number of sharks, \
1189 dolphins, and whales. The swimming motions are great. Originally \
1190 written by Mark Kilgard.
1192 *hacks.lament.documentation: \
1193 Animates a simulation of Lemarchand's Box, repeatedly solving itself. \
1194 Requires OpenGL, and a machine with fast hardware support for texture \
1195 maps. Warning: occasionally opens doors. Written by Jamie Zawinski.
1197 *hacks.bubble3d.name: Bubble3D
1198 *hacks.bubble3d.documentation: \
1199 Draws a stream of rising, undulating 3D bubbles, rising toward the \
1200 top of the screen, with nice specular reflections. Written by Richard \
1203 *hacks.glplanet.name: GLPlanet
1204 *hacks.glplanet.documentation: \
1205 Draws a planet bouncing around in space. Written by David Konerding. \
1206 The built-in image is a map of the earth (extracted from `xearth'), \
1207 but you can wrap any texture around the sphere, e.g., the planetary \
1208 textures that come with `ssystem'.
1210 *hacks.pulsar.documentation: \
1211 Draws some intersecting planes, making use of alpha blending, fog, \
1212 textures, and mipmaps, plus a ``frames per second'' meter so that you \
1213 can tell how fast your graphics card is... Requires OpenGL. Written \
1216 *hacks.extrusion.documentation: \
1217 Draws various rotating extruded shapes that twist around, lengthen, \
1218 and turn inside out. Created by David Konerding from the samples \
1219 that come with the GL Extrusion library by Linas Vepstas.
1221 *hacks.sierpinski3d.name: Sierpinski3D
1222 *hacks.sierpinski3d.documentation: \
