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.

99 ! but seems to work fine with mwm and olwm. Try it and see. If your

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

331 ! To display a randomized slideshow of images, you can do something like this:
333 ! default-n: "Slideshow" xv -root -rmode 5 -random -viewonly \
334 ! -wloop -wait 30 $HOME/bitmaps/*.jpg \n\
336 ! Recipes for using other slideshow programs can be found in the
337 ! XScreenSaver FAQ: http://www.jwz.org/xscreensaver/faq.html
339 ! Note that we've used "default-n" as the visual name, rather than just
340 ! "default": this means "default visual, no install", that is, it's like
341 ! specifying the command-line arguments "-visual default -no-install".
342 ! This is necessary because, when XV or XLI arerunning in "-root" mode, they
343 ! always assume that the default visual and colormap are being used, rather
344 ! than examining the window it is drawing on to see what visual and colormap
345 ! it has. If we didn't force the default visual to be used, we would get an
346 ! X error. If we didn't force the default colormap to be installed, the
347 ! colors would be all wrong. "default-i" may also be used as a visual name
348 ! (meaning, "-visual default -install") but you probably won't ever need
352 ! Some of the GL demos that SGI ships work with XScreenSaver; most don't.
353 ! XScreenSaver includes a program (not built or installed by default)
354 ! called "xscreensaver-sgigl". To use the SGI demos with XScreenSaver,
355 ! build that program, and use it to launch the SGI demos. For example,
356 ! on Irix 6.2, you can do this:
358 ! xscreensaver-sgigl /usr/demos/bin/ep -S
359 ! xscreensaver-sgigl /usr/demos/bin/bongo
361 ! On Irix 6.3, things have moved, so you need to do it like this:
363 ! xscreensaver-sgigl /usr/sbin/ep -S
365 ! (But note that, on non-SGIs, the bundled "stonerview" hack is a decent
366 ! clone of "ep". Yay!)
368 ! You can also use the "ant" demo, but first you need to wrap a shell script
369 ! around it that cds to its home directory, so that it can find its files;
370 ! and also pass it the -S argument, to prevent it from forking. What a mess!
371 ! Basically, the SGI demo writers went out of their way to make my life hell.

564 *hacks.documentation.isInstalled: True
566 *hacks.qix.documentation: \
567 This is the swiss army chainsaw of qix programs. It bounces a series \
568 of line segments around the screen, and uses variations on this basic \
569 motion pattern to produce all sorts of different presentations: line \
570 segments, filled polygons, overlapping translucent areas... Written \
573 *hacks.attraction.documentation: \
574 Like qix, this uses a simple simple motion model to generate many \
575 different display modes. The control points attract each other up to \
576 a certain distance, and then begin to repel each other. The \
577 attraction/repulsion is proportional to the distance between any two \
578 particles, similar to the strong and weak nuclear forces. \
580 One of the most interesting ways to watch this hack is simply as \
581 bouncing balls, because their motions and interactions with each \
582 other are so odd. Sometimes two balls will get into a tight orbit \
583 around each other, to be interrupted later by a third, or by the edge \
584 of the screen. It looks quite chaotic. \
586 Written by Jamie Zawinski, based on Lisp code by John Pezaris.
588 *hacks.pyro.documentation: \
589 Pyro draws exploding fireworks. Blah blah blah. Written by Jamie \
592 *hacks.helix.documentation: \
593 This repeatedly generates spirally string-art-ish patterns. Written \
596 *hacks.pedal.documentation: \
597 This is sort of a combination spirograph/string-art. It generates a \
598 large, complex polygon, and lets the X server do the bulk of the work \
599 by giving it an even/odd winding rule. Written by Dale Moore, based \
600 on some ancient PDP-11 code.
602 *hacks.rorschach.documentation: \
603 This generates random inkblot patterns. The algorithm is deceptively \
604 simple for how well it works; it merely walks a dot around the screen \
605 randomly, and then reflects the image horizontally, vertically, or \
606 both. Any deep-seated neurotic tendencies which this program reveals \
607 are your own problem. Written by Jamie Zawinski.
609 *hacks.hopalong.documentation: \
610 This draws lacy fractal patterns, based on iteration in the imaginary \
611 plane, from a 1986 Scientific American article. Mostly written by \
614 *hacks.greynetic.documentation: \
615 This draws random colored and stippled rectangles. Written by Jamie \
618 *hacks.imsmap.name: IMSmap
619 *hacks.imsmap.documentation: \
620 This generates random cloud-like patterns. It looks quite different \
621 in monochrome and color. The basic idea is to take four points on \
622 the edge of the image, and assign each a random ``elevation''. Then \
623 find the point between them, and give it a value which is the average \
624 of the other four, plus some small random offset. Then coloration is \
625 done based on elevation. \
627 The color selection is done by binding the elevation to either hue, \
628 saturation, or brightness, and assigning random values to the others. \
629 The ``brightness'' mode tends to yield cloudlike patterns, and the \
630 others tend to generate images that look like heat-maps or CAT-scans. \
631 Written by Juergen Nickelsen and Jamie Zawinski.
633 *hacks.slidescreen.name: SlideScreen
634 *hacks.slidescreen.documentation: \
635 This takes an image, divides it into a grid, and then randomly shuffles \
636 the squares around as if it was one of those annoying ``16-puzzle'' \
637 games, where there is a grid of squares, one of which is missing. \
638 I hate trying to solve those puzzles, but watching one permute itself \
639 is more amusing. Written by Jamie Zawinski.
641 *hacks.decayscreen.name: DecayScreen
642 *hacks.decayscreen.documentation: \
643 This takes an image and makes it melt. You've no doubt seen this \
644 effect before, but no screensaver would really be complete without it. \
645 It works best if there's something colorful visible. Warning, if the \
646 effect continues after the screen saver is off, seek medical attention. \
647 Written by David Wald and Vivek Khera.
649 *hacks.jigsaw.documentation: \
650 This grabs a screen image, carves it up into a jigsaw puzzle, \
651 shuffles it, and then solves the puzzle. This works especially well \
652 when you feed it an external video signal instead of letting it grab \
653 the screen image (actually, I guess this is generally true...) When \
654 it is grabbing a video image, it is sometimes pretty hard to guess \
655 what the image is going to look like once the puzzle is solved. \

660 The ``blitspin'' hack repeatedly rotates a bitmap by 90 degrees by \
661 using logical operations: the bitmap is divided into quadrants, and \
662 the quadrants are shifted clockwise. Then the same thing is done \
663 again with progressively smaller quadrants, except that all \
664 sub-quadrants of a given size are rotated in parallel. Written by \
665 Jamie Zawinski based on some cool SmallTalk code seen in in Byte \
668 As you watch it, the image appears to dissolve into static and then \
669 reconstitute itself, but rotated. You can provide the image to use, \
670 as an XBM or XPM file, or tell it to grab a screen image and rotate \
673 *hacks.slip.documentation: \
674 This program throws some random bits on the screen, then sucks them \
675 through a jet engine and spews them out the other side. To avoid \
676 turning the image completely to mush, every now and then it will and \
677 then it interjects some splashes of color into the scene, or go into \
678 a spin cycle, or stretch the image like taffy, or (this is my \
679 addition) grab an image of your current desktop to chew on. \
680 Originally written by Scott Draves; whacked on by Jamie Zawinski.
682 *hacks.distort.documentation: \
683 This hack grabs an image of the screen, and then lets a transparent \
684 lens wander around the screen, magnifying whatever is underneath. \
685 Written by Jonas Munsin.
687 *hacks.spotlight.documentation: \
688 Draws a spotlight scanning across a black screen, illumnating the \
689 underlying desktop when it passes. Written by Rick Schultz.
691 *hacks.hypercube.documentation: \
692 This displays 2D projections of the sequence of 3D objects which are \
693 the projections of the 4D analog to the cube: as a square is composed \
694 of four lines, each touching two others; and a cube is composed of \
695 six squares, each touching four others; a hypercube is composed of \
696 eight cubes, each touching six others. To make it easier to \
697 visualize the rotation, it uses a different color for the edges of \
698 each face. Don't think about it too long, or your brain will melt. \
699 Written by Joe Keane, Fritz Mueller, and Jamie Zawinski.
701 *hacks.hyperball.documentation: \
702 Hyperball is to hypercube as dodecahedron is to cube: this displays \
703 a 2D projection of the sequence of 3D objects which are the projections \
704 of the 4D analog to the dodecahedron. Written by Joe Keane.
706 *hacks.halo.documentation: \
707 This draws trippy psychedelic circular patterns that hurt to look at. \
708 It can also animate the control-points, but that takes a lot of CPU \
709 and bandwidth. Written by Jamie Zawinski.
711 *hacks.maze.documentation: \
712 This is the ancient X maze demo, modified to work with xscreensaver. \
713 It generates a random maze, then solves it with visual feedback. \
714 Originally by Jim Randell; modified by a cast of thousands.
716 *hacks.noseguy.documentation: \
717 A little man with a big nose wanders around your screen saying \
718 things. The things which he says can come from a file, or from an \
719 external program like `zippy' or `fortune'. This was extracted from \
720 `xnlock' by Dan Heller. Colorized by Jamie Zawinski.
722 *hacks.flame.documentation: \
723 Another iterative fractal generator. Written by Scott Draves.
725 *hacks.lmorph.name: LMorph
726 *hacks.lmorph.documentation: \
727 This generates random spline-ish line drawings and morphs between \
728 them. Written by Sverre H. Huseby and Glenn T. Lines.
730 *hacks.deco.documentation: \
731 This one subdivides and colors rectangles randomly. It looks kind of \
732 like Brady-Bunch-era rec-room wall paneling. (Raven says: ``this \
733 screensaver is ugly enough to peel paint.'') Written by Jamie \
734 Zawinski, inspired by Java code by Michael Bayne.
736 *hacks.moire.documentation: \
737 This one draws cool circular interference patterns. Most of the \
738 circles you see aren't explicitly rendered, but show up as a result \
739 of interactions between the other pixels that were drawn. Written by \
740 Jamie Zawinski, inspired by Java code by Michael Bayne. As he \
741 pointed out, the beauty of this one is that the heart of the display \
742 algorithm can be expressed with just a pair of loops and a handful of \
743 arithmetic, giving it a high ``display hack metric''.
745 *hacks.moire2.documentation: \
746 Another example of the fun you can have with moire \
747 interference patterns; this hack generates fields of concentric \
748 circles or ovals, and combines the planes with various operations. \
749 The planes are moving independently of one another, causing the \
750 interference lines to ``spray.'' Written by Jamie Zawinski.
752 *hacks.lightning.documentation: \
753 This one draws crackling fractal lightning bolts. It's simple, \
754 direct, and to the point. If only it had sound... Written by Keith \
757 *hacks.strange.documentation: \
758 This draws strange attractors: it's a colorful, \
759 unpredictably-animating field of dots that swoops and twists around. \
760 The motion is very nice. Written by Massimino Pascal.
762 *hacks.spiral.documentation: \
763 Moving circular patterns, by Peter Schmitzberger. Moving circular \
764 patterns means moire; interference patterns, of course.
766 *hacks.laser.documentation: \
767 Moving radiating lines, that look vaguely like scanning laser beams. \
768 Written by Pascal Pensa. (Frankie say: relax.)
770 *hacks.grav.documentation: \
771 This program draws a simple orbital simulation. If you turn on \
772 trails, it looks kind of like a cloud-chamber photograph. Written \
775 *hacks.drift.documentation: \
776 How could one possibly describe this except as ``drifting recursive \
777 fractal cosmic flames?'' Another fine hack from the Scott Draves \
778 collection of fine hacks.
781 *hacks.ifs.documentation: \
782 This one draws spinning, colliding iterated-function-system images. \
783 Written by Massimino Pascal.
785 *hacks.julia.documentation: \
786 This one draws spinning, animating (are you detecting a pattern here \
787 yet?) explorations of the Julia set. You've probably seen static \
788 images of this fractal form before, but it's a lot of fun to watch in \
789 motion as well. One interesting thing is that there is a small \
790 swinging dot passing in front of the image, which indicates the \
791 control point from which the rest of the image was generated. \
792 Written by Sean McCullough.
794 *hacks.penrose.documentation: \
795 Draws quasiperiodic tilings; think of the implications on modern \
796 formica technology. Written by Timo Korvola. \
798 In April 1997, Sir Roger Penrose, a British math professor who has \
799 worked with Stephen Hawking on such topics as relativity, black \
800 holes, and whether time has a beginning, filed a \
801 copyright-infringement lawsuit against the Kimberly-Clark \
802 Corporation, which Penrose said copied a pattern he created (a \
803 pattern demonstrating that ``a nonrepeating pattern could exist in \
804 nature'') for its Kleenex quilted toilet paper. Penrose said he \
805 doesn't like litigation but, ``When it comes to the population of \
806 Great Britain being invited by a multinational to wipe their bottoms \
807 on what appears to be the work of a Knight of the Realm, then a last \
808 stand must be taken.'' \
810 As reported by News of the Weird #491, 4-jul-1997.
812 *hacks.sierpinski.documentation: \
813 This draws the two-dimensional variant of the recursive Sierpinski \
814 triangle fractal. Written by Desmond Daignault.
816 *hacks.braid.documentation: \
817 Draws random color-cycling inter-braided concentric circles. Written \
820 *hacks.galaxy.documentation: \
821 This draws spinning galaxies, which then collide and scatter their \
822 stars to the, uh, four winds or something. Originally an Amiga \
823 program by Uli Siegmund.
825 *hacks.bouboule.documentation: \
826 This draws what looks like a spinning, deforming baloon with \
827 varying-sized spots painted on its invisible surface. Written by \
830 *hacks.swirl.documentation: \
831 More flowing, swirly patterns. This version is by M. Dobie and R. \
832 Taylor, but you might have seen a Mac program similar to this called \
833 FlowFazer. There is also a cool Java applet of a similar concept
835 *hacks.flag.documentation: \
836 This draws a waving colored flag, that undulates its way around the \
837 screen. The trick is the flag can contain arbitrary text and images. \
838 By default, it displays either the current system name and OS \
839 type, or a picture of ``Bob,'' but you can replace the text or the \
840 image with a command-line option. Written by Charles Vidal and Jamie \
843 *hacks.sphere.documentation: \
844 Another of the classic screenhacks of the distant past, this one \
845 draws shaded spheres in multiple colors. This hack traces its \
846 lineage back to Tom Duff in 1982.
848 *hacks.forest.documentation: \
849 This draws fractal trees. Written by Peter Baumung. Everybody loves \
852 *hacks.lisa.documentation: \
853 This draws Lisajous loops, by Caleb Cullen. Remember that device \
854 they had the Phantom Zone prisoners in during their trial in \
855 Superman? I think that was one of these.
857 *hacks.lissie.documentation: \
858 Another Lissajous figure. This one draws the progress of circular \
859 shapes along a path. Written by Alexander Jolk.
861 *hacks.goop.documentation: \
862 This draws set of animating, transparent, amoeba-like blobs. The \
863 blobs change shape as they wander around the screen, and they are \
864 translucent, so you can see the lower blobs through the higher ones, \
865 and when one passes over another, their colors merge. Written by \
866 Jamie Zawinski. I got the idea for this from a cool mouse pad I \
867 have, which achieves the same kind of effect in real life by having \
868 several layers plastic with colored oil between them. Written by \
871 *hacks.starfish.documentation: \
872 This generates a sequence of undulating, throbbing, star-like \
873 patterns which pulsate, rotate, and turn inside out. Another display \
874 mode uses these shapes to lay down a field of colors, which are then \
875 cycled. The motion is very organic. Written by Jamie Zawinski.
877 *hacks.munch.documentation: \n\
884 As reported by HAKMEM, in 1962, Jackson Wright wrote the above PDP-1 \
885 code. That code still lives on in this screenhack, some 35 years \
886 later. The number of lines of enclosing code has increased \
887 substantially, however. This version is by Tim Showalter.
889 *hacks.fadeplot.name: FadePlot
890 *hacks.fadeplot.documentation: \
891 Draws what looks like a waving ribbon following a sinusoidal path. \
892 Written by Bas van Gaalen and Charles Vidal.
894 *hacks.coral.documentation: \
895 Simulates coral growth, albeit somewhat slowly. This image doesn't \
896 really do it justice. Written by Frederick Roeber.
898 *hacks.mountain.documentation: \
899 Generates random 3d plots that look vaguely mountainous. Written by \
902 *hacks.triangle.documentation: \
903 Generates random mountain ranges using iterative subdivision of \
904 triangles. Written by Tobias Gloth.
906 *hacks.worm.documentation: \
907 An ancient xlock hack that draws multicolored worms that crawl around \
908 the screen. Written by Brad Taylor, Dave Lemke, Boris Putanec, and \
911 *hacks.rotor.documentation: \
912 Another ancient xlock demo, this one by Tom Lawrence. It draws a \
913 line segment moving along a complex spiraling curve. I tweaked this \
914 to generate curvier lines, but still frames of it don't look like \
917 *hacks.ant.documentation: \
918 A cellular automaton that is really a two-dimensional Turing machine: \
919 as the heads (``ants'') walk along the screen, they change pixel \
920 values in their path. Then, as they pass over changed pixels, their \
921 behavior is influenced. Written by David Bagley.
923 *hacks.demon.documentation: \
924 A cellular automaton that starts with a random field, and organizes \
925 it into stripes and spirals. Written by David Bagley.
927 *hacks.loop.documentation: \
928 This one produces loop-shaped colonies that spawn, age, and \
929 eventually die. Written by David Bagley.
931 *hacks.vines.documentation: \
932 This one generates a continuous sequence of small, curvy geometric \
933 patterns. It scatters them around your screen until it fills up, \
934 then it clears the screen and starts over. Written by Tracy Camp and \
937 *hacks.kaleidescope.documentation: \
938 Another clone of an ancient meme, consisting largely of frenetic \
939 rotational motion of colored lines. This one is by Ron Tapia. The \
940 motion is nice, but I think it needs more solids, or perhaps just \
941 brighter colors. More variations in the rotational speed might help, \
944 *hacks.xjack.documentation: \
945 This program behaves schizophrenically and makes a lot of typos. \
946 Written by Jamie Zawinski. If you haven't seen Stanley Kubrick's \
947 masterpiece, ``The Shining,'' you won't get it. Those who have \
948 describe this hack as ``inspired.''
950 *hacks.xlyap.documentation: \
951 This generates pretty fractal pictures by doing funky math involving \
952 the ``Lyapunov exponent.'' It has a cool interactive mode, too. \
953 Written by Ron Record.
955 *hacks.cynosure.documentation: \
956 A hack similar to `greynetic', but less frenetic. The first \
957 implementation was by Stephen Linhart; then Ozymandias G. Desiderata \
958 wrote a Java applet clone. That clone was discovered by Jamie \
959 Zawinski, and ported to C for inclusion here.
961 *hacks.flow.documentation: \
962 Another series of strange attractors: a flowing series of points, \
963 making strange rotational shapes. Written by Jeff Butterworth.
965 *hacks.epicycle.documentation: \
966 This program draws the path traced out by a point on the edge of a \
967 circle. That circle rotates around a point on the rim of another \
968 circle, and so on, several times. These were the basis for the \
969 pre-heliocentric model of planetary motion. Written by James \
972 *hacks.interference.documentation: \
973 Another color-field hack, this one works by computing decaying \
974 sinusoidal waves, and allowing them to interfere with each other as \
975 their origins move. Written by Hannu Mallat.
977 *hacks.truchet.documentation: \
978 This draws line- and arc-based Truchet patterns that tile the screen. \
979 Written by Adrian Likins.
981 *hacks.bsod.name: BSOD
982 *hacks.bsod.documentation: \
983 BSOD stands for ``Blue Screen of Death.'' The finest in personal \
984 computer emulation, this hack simulates popular screen savers from a \
985 number of less robust operating systems. Written by Jamie Zawinski.
987 *hacks.crystal.documentation: \
988 Moving polygons, similar to a kaleidescope (more like a kaleidescope \
989 than the hack called `kaleid,' actually.) This one by Jouk Jansen.
991 *hacks.discrete.documentation: \
992 More ``discrete map'' systems, including new variants of Hopalong and \
993 Julia, and a few others. Written by Tim Auckland.
995 *hacks.kumppa.documentation: \
996 Spiraling, spinning, and very, very fast splashes of color rush \
997 toward the screen. Written by Teemu Suutari.
999 *hacks.rd-bomb.name: RD-Bomb
1000 *hacks.rd-bomb.documentation: \
1001 Another variation of the `Bomb' program by Scott Draves. This draws \
1002 a grid of growing square-like shapes that, once they overtake each \
1003 other, react in unpredictable ways. ``RD'' stands for \
1006 *hacks.sonar.documentation: \
1007 This program draws a simulation of a sonar screen. Written by \
1008 default, it displays a random assortment of ``bogies'' on the screen, \
1009 but if compiled properly, it can ping (pun intended) your local \
1010 network, and actually plot the proximity of the other hosts on your \
1011 network to you. It would be easy to make it monitor other sources of \
1012 data, too. (Processes? Active network connections? CPU usage per \
1013 user?) Written by Stephen Martin.
1015 *hacks.t3d.name: T3D
1016 *hacks.t3d.documentation: \
1017 This draws a working analog clock composed of floating, throbbing \
1018 bubbles. Written by Bernd Paysan.
1020 *hacks.penetrate.documentation: \
1021 This hack simulates the classic arcade game Missile Command. Written \
1024 *hacks.deluxe.documentation: \
1025 This draws a pulsing sequence of stars, circles, and lines. It would \
1026 look better if it was faster, but as far as I can tell, there is no \
1027 way to make this be both: fast, and flicker-free. Yet another reason \
1028 X sucks. Written by Jamie Zawinski.
1030 *hacks.compass.documentation: \
1031 This draws a compass, with all elements spinning about randomly, for \
1032 that ``lost and nauseous'' feeling. Written by Jamie Zawinski.
1034 *hacks.squiral.documentation: \
1035 Draws a set of interacting, square-spiral-producing automata. The \
1036 spirals grow outward until they hit something, then they go around \
1037 it. Written by Jeff Epler.
1039 *hacks.xflame.documentation: \
1040 Draws a simulation of pulsing fire. It can also take an arbitrary \
1041 image and set it on fire too. Written by Carsten Haitzler, hacked on \
1044 *hacks.wander.documentation: \
1045 Draws a colorful random-walk, in various forms. Written by Rick \
1048 *hacks.critical.documentation: \
1049 Draws a system of self-organizing lines. It starts out as random \
1050 squiggles, but after a few iterations, order begins to appear. \
1051 Written by Martin Pool.
1053 *hacks.phosphor.documentation: \
1054 Draws a simulation of an old terminal, with large pixels and \
1055 long-sustain phosphor. It can run any program as a source of the text \
1056 it displays. Written by Jamie Zawinski.
1058 *hacks.xmatrix.documentation: \
1059 A rendition of the text scrolls seen in the movie ``The Matrix.'' \
1060 Written by Jamie Zawinski.
1062 *hacks.petri.documentation: \
1063 This simulates colonies of mold growing in a petri dish. Growing \
1064 colored circles overlap and leave spiral interference in their wake. \
1065 Written by Dan Bornstein.
1067 *hacks.shadebobs.name: ShadeBobs
1068 *hacks.shadebobs.documentation: \
1069 This draws smoothly-shaded oscilating oval patterns, that look \
1070 something like vapor trails or neon tubes. Written by Shane Smit.
1072 *hacks.ccurve.name: C Curve
1073 *hacks.ccurve.documentation: \
1074 Generates self-similar linear fractals, including the classic ``C \
1075 Curve.'' Written by Rick Campbell.
1077 *hacks.blaster.documentation: \
1078 Draws a simulation of flying space-combat robots (cleverly disguised \
1079 as colored circles) doing battle in front of a moving star field. \
1080 Written by Jonathan Lin.
1082 *hacks.bumps.documentation: \
1083 A bit like `Spotlight', except that instead of merely exposing part \
1084 of your desktop, it creates a bump map from it. Basically, it \
1085 3D-izes a roaming section of your desktop, based on color intensity. \
1086 Written by Shane Smit.
1088 *hacks.xteevee.name: XTeeVee
1089 *hacks.xteevee.documentation: \
1090 XTeeVee simulates various television problems, including static, \
1091 loss of vertical hold, and a test pattern. By Greg Knauss.
1093 *hacks.xspirograph.name: XSpiroGraph
1094 *hacks.xspirograph.documentation: \
1095 Simulates that pen-in-nested-plastic-gears toy from your childhood. \
1098 *hacks.nerverot.name: NerveRot
1099 *hacks.nerverot.documentation: \
1100 Draws different shapes composed of nervously vibrating squiggles, \
1101 as if seen through a camera operated by a monkey on crack. \
1104 *hacks.webcollage.name: WebCollage
1105 *hacks.webcollage.documentation: \
1106 This program makes collages out of random images pulled off of the \
1107 World Wide Web. It finds these images by doing random web searches, \
1108 and then extracting images from the returned pages. It can also be \
1109 set up to filter the images through the `VidWhacker' program, above, \
1110 which looks really great. \
1112 (Note that most of the images it finds are text, and not pictures. \
1113 This is because most of the web is pictures of text. Which is pretty \
1114 sad.) Written by Jamie Zawinski.
1116 *hacks.vidwhacker.name: VidWhacker
1117 *hacks.vidwhacker.documentation: \
1118 This is actually just a shell script that grabs a frame of video from \
1119 the system's video input, and then uses some PBM filters (chosen at \
1120 random) to manipulate and recombine the video frame in various ways \
1121 (edge detection, subtracting the image from a rotated version of \
1122 itself, etc.) Then it displays that image for a few seconds, and \
1123 does it again. This works really well if you just feed broadcast \
1124 television into it. \
1126 Currently, the three lines of the script that actually grab the \
1127 source picture are SGI specific, but it should be trivial to adapt it \
1128 to work on other systems that can grab video (please send me the \
1129 changes if you do this...)
1131 *hacks.rocks.documentation: \
1132 This draws an animation of flight through an asteroid field, with \
1133 changes in rotation and direction. It can also display 3D \
1134 separations for red/blue glasses! Mostly written by Jamie Zawinski.
1136 *hacks.bubbles.documentation: \
1137 This simulates the kind of bubble formation that happens when water \
1138 boils:small bubbles appear, and as they get closer to each other, \
1139 they combine to form larger bubbles, which eventually pop. Written \
1142 *hacks.gears.documentation: \
1143 This draws sets of turning, interlocking gears, rotating in three \
1144 dimensions. Another GL hack, by Danny Sung, Brian Paul, Ed Mackey, \
1147 *hacks.superquadrics.documentation: \
1148 Ed Mackey reports that he wrote the first version of this program in \
1149 BASIC on a Commodore 64 in 1987, as a 320x200 black and white \
1150 wireframe. Now it is GL and has specular reflections.
1152 *hacks.morph3d.name: Morph3D
1153 *hacks.morph3d.documentation: \
1154 Another 3d shape-changing GL hack, by Marcelo Vianna. It has the \
1155 same shiny-plastic feel as Superquadrics, as many computer-generated \
1158 *hacks.cage.documentation: \
1159 This draws Escher's ``Impossible Cage,'' a 3d analog of a moebius \
1160 strip, and rotates it in three dimensions. Written by Marcelo \
1163 *hacks.moebius.documentation: \
1164 Another M. C. Escher hack by Marcelo Vianna, this one draws \
1165 ``Moebius Strip II,'' a GL image of ants walking along the surface of \
1168 *hacks.stairs.documentation: \
1169 by Marcelo Vianna's third Escher GL hack, this one draws an \
1170 ``infinite'' staircase.
1172 *hacks.pipes.documentation: \
1173 If you've ever been in the same room with a Windows NT machine, \
1174 you've probably seen this GL hack. This version is by Marcelo \
1177 *hacks.sproingies.documentation: \
1178 Q-Bert meets Marble Madness! Written by Ed Mackey.
1180 *hacks.rubik.documentation: \
1181 Draws a Rubik's Cube that rotates in three dimensions and repeatedly \
1182 shuffles and solves itself. Another fine GL hack by Marcelo Vianna.
1184 *hacks.atlantis.documentation: \
1185 This is xfishtank writ large: a GL animation of a number of sharks, \
1186 dolphins, and whales. The swimming motions are great. Originally \
1187 written by Mark Kilgard.
1189 *hacks.lament.documentation: \
1190 Animates a simulation of Lemarchand's Box, repeatedly solving itself. \
1191 Requires OpenGL, and a machine with fast hardware support for texture \
1192 maps. Warning: occasionally opens doors. Written by Jamie Zawinski.
1194 *hacks.bubble3d.name: Bubble3D
1195 *hacks.bubble3d.documentation: \
1196 Draws a stream of rising, undulating 3D bubbles, rising toward the \
1197 top of the screen, with nice specular reflections. Written by Richard \
1200 *hacks.glplanet.name: GLPlanet
1201 *hacks.glplanet.documentation: \
1202 Draws a planet bouncing around in space. Written by David Konerding. \
1203 The built-in image is a map of the earth (extracted from `xearth'), \
1204 but you can wrap any texture around the sphere, e.g., the planetary \
1205 textures that come with `ssystem'.
1207 *hacks.pulsar.documentation: \
1208 Draws some intersecting planes, making use of alpha blending, fog, \
1209 textures, and mipmaps, plus a ``frames per second'' meter so that you \
1210 can tell how fast your graphics card is... Requires OpenGL. Written \
1213 *hacks.extrusion.documentation: \
1214 Draws various rotating extruded shapes that twist around, lengthen, \
1215 and turn inside out. Created by David Konerding from the samples \
1216 that come with the GL Extrusion library by Linas Vepstas.
1218 *hacks.sierpinski3d.name: Sierpinski3D
1219 *hacks.sierpinski3d.documentation: \
1220 This draws the three-dimensional variant of the recursive Sierpinski \
1221 triangle fractal, using GL. Written by Tim Robinson and Jamie Zawinski.
1223 *hacks.ripples.documentation: \
1224 This draws rippling interference patterns like splashing water. \
1225 With the -water option, it manipulates your desktop image to look \
