Then coloration is \ -done based on elevation. \ - \n\n\ -The color selection is done by binding the elevation to either hue, \ -saturation, or brightness, and assigning random values to the others. \ -The ``brightness'' mode tends to yield cloudlike patterns, and the \ -others tend to generate images that look like heat-maps or CAT-scans. \ -Written by Juergen Nickelsen and Jamie Zawinski. - -*hacks.slidescreen.name: SlideScreen -*hacks.slidescreen.documentation: \ -This grabs an image of whatever is on your screen, divides it into a \ -grid, and then randomly shuffles the squares around as if it was one \ -of those annoying ``16-puzzle'' games, where there is a grid of \ -squares, one of which is missing. I hate trying to solve those \ -puzzles, but watching one permute itself is more amusing. Written by \ -Jamie Zawinski. - -*hacks.decayscreen.name: DecayScreen -*hacks.decayscreen.documentation: \ -This grabs an image of whatever is on your screen, and makes it melt. \ -You've no doubt seen this effect before, but no screensaver would \ -really be complete without it. It works best if there's something \ -colorful visible. Warning, if the effect continues after the screen \ -saver is off, seek medical attention. Written by David Wald and \ -Vivek Khera. \ - \n\n\ -A number of these screenhacks have the ability to take an image of \ -your desktop and manipulate it in some way. On SGI systems, these \ -programs are able to (at random) pull their source image from the \ -system's video input instead! This works nicely if you leave some \ -some random television station plugged in. - -*hacks.jigsaw.documentation: \ -This grabs a screen image, carves it up into a jigsaw puzzle, \ -shuffles it, and then solves the puzzle. This works especially well \ -when you feed it an external video signal instead of letting it grab \ -the screen image (actually, I guess this is generally true...) When \ -it is grabbing a video image, it is sometimes pretty hard to guess \ -what the image is going to look like once the puzzle is solved. \ -Written by Jamie Zawinski. - -*hacks.blitspin.name: BlitSpin -*hacks.blitspin.documentation: \ -The ``blitspin'' hack repeatedly rotates a bitmap by 90 degrees by \ -using logical operations: the bitmap is divided into quadrants, and \ -the quadrants are shifted clockwise. Then the same thing is done \ -again with progressively smaller quadrants, except that all \ -sub-quadrants of a given size are rotated in parallel. Written by \ -Jamie Zawinski based on some cool SmallTalk code seen in in Byte \ -Magazine in 1981. \ - \n\n\ -As you watch it, the image appears to dissolve into static and then \ -reconstitute itself, but rotated. You can provide the image to use, \ -as an XBM or XPM file, or tell it to grab a screen image and rotate \ -that. - -*hacks.slip.documentation: \ -This program throws some random bits on the screen, then sucks them \ -through a jet engine and spews them out the other side. To avoid \ -turning the image completely to mush, every now and then it will and \ -then it interjects some splashes of color into the scene, or go into \ -a spin cycle, or stretch the image like taffy, or (this is my \ -addition) grab an image of your current desktop to chew on. \ -Originally written by Scott Draves; whacked on by Jamie Zawinski. - -*hacks.distort.documentation: \ -This hack grabs an image of the screen, and then lets a transparent \ -lens wander around the screen, magnifying whatever is underneath. \ -Written by Jonas Munsin. - -*hacks.spotlight.documentation: \ -Draws a spotlight scanning across a black screen, illumnating the \ -underlying desktop when it passes. Written by Rick Schultz. - -*hacks.hypercube.documentation: \ -This displays 2D projections of the sequence of 3D objects which are \ -the projections of the 4D analog to the cube: as a square is composed \ -of four lines, each touching two others; and a cube is composed of \ -six squares, each touching four others; a hypercube is composed of \ -eight cubes, each touching six others. To make it easier to \ -visualize the rotation, it uses a different color for the edges of \ -each face. Don't think about it too long, or your brain will melt. \ -Written by Joe Keane, Fritz Mueller, and Jamie Zawinski. - -*hacks.halo.documentation: \ -This draws trippy psychedelic circular patterns that hurt to look at. \ -It can also animate the control-points, but that takes a lot of CPU \ -and bandwidth. Written by Jamie Zawinski. - -*hacks.maze.documentation: \ -This is the ancient X maze demo, modified to work with xscreensaver. \ -It generates a random maze, then solves it with visual feedback. \ -Originally by Jim Randell; modified by a cast of thousands. - -*hacks.noseguy.documentation: \ -A little man with a big nose wanders around your screen saying \ -things. The things which he says can come from a file, or from an \ -external program like `zippy' or `fortune'. This was extracted from \ -`xnlock' by Dan Heller. Colorized by Jamie Zawinski. - -*hacks.flame.documentation: \ -Another iterative fractal generator. Written by Scott Draves. - -*hacks.lmorph.name: LMorph -*hacks.lmorph.documentation: \ -This generates random spline-ish line drawings and morphs between \ -them. Written by Sverre H. Huseby and Glenn T. Lines. - -*hacks.deco.documentation: \ -This one subdivides and colors rectangles randomly. It looks kind of \ -like Brady-Bunch-era rec-room wall paneling. (Raven says: ``this \ -screensaver is ugly enough to peel paint.'') Written by Jamie \ -Zawinski, inspired by Java code by Michael Bayne. - -*hacks.moire.documentation: \ -This one draws cool circular interference patterns. Most of the \ -circles you see aren't explicitly rendered, but show up as a result \ -of interactions between the other pixels that were drawn. Written by \ -Jamie Zawinski, inspired by Java code by Michael Bayne. As he \ -pointed out, the beauty of this one is that the heart of the display \ -algorithm can be expressed with just a pair of loops and a handful of \ -arithmetic, giving it a high ``display hack metric''. - -*hacks.moire2.documentation: \ -Another example of the fun you can have with moire \ -interference patterns; this hack generates fields of concentric \ -circles or ovals, and combines the planes with various operations. \ -The planes are moving independently of one another, causing the \ -interference lines to ``spray.'' Written by Jamie Zawinski. - -*hacks.lightning.documentation: \ -This one draws crackling fractal lightning bolts. It's simple, \ -direct, and to the point. If only it had sound... Written by Keith \ -Romberg. - -*hacks.strange.documentation: \ -This draws strange attractors: it's a colorful, \ -unpredictably-animating field of dots that swoops and twists around. \ -The motion is very nice. Written by Massimino Pascal. - -*hacks.spiral.documentation: \ -Moving circular patterns, by Peter Schmitzberger. Moving circular \ -patterns means moire; interference patterns, of course. - -*hacks.laser.documentation: \ -Moving radiating lines, that look vaguely like scanning laser beams. \ -Written by Pascal Pensa. (Frankie say: relax.) - -*hacks.grav.documentation: \ -This program draws a simple orbital simulation. If you turn on \ -trails, it looks kind of like a cloud-chamber photograph. Written \ -by Greg Bowering. - -*hacks.drift.documentation: \ -How could one possibly describe this except as ``drifting recursive \ -fractal cosmic flames?'' Another fine hack from the Scott Draves \ -collection of fine hacks. - -*hacks.ifs.name: IFS -*hacks.ifs.documentation: \ -This one draws spinning, colliding iterated-function-system images. \ -Written by Massimino Pascal. - -*hacks.julia.documentation: \ -This one draws spinning, animating (are you detecting a pattern here \ -yet?) explorations of the Julia set. You've probably seen static \ -images of this fractal form before, but it's a lot of fun to watch in \ -motion as well. One interesting thing is that there is a small \ -swinging dot passing in front of the image, which indicates the \ -control point from which the rest of the image was generated. \ -Written by Sean McCullough. - -*hacks.penrose.documentation: \ -Draws quasiperiodic tilings; think of the implications on modern \ -formica technology. Written by Timo Korvola. \ - \n\n\ -In April 1997, Sir Roger Penrose, a British math professor who has \ -worked with Stephen Hawking on such topics as relativity, black \ -holes, and whether time has a beginning, filed a \ -copyright-infringement lawsuit against the Kimberly-Clark \ -Corporation, which Penrose said copied a pattern he created (a \ -pattern demonstrating that ``a nonrepeating pattern could exist in \ -nature'') for its Kleenex quilted toilet paper. Penrose said he \ -doesn't like litigation but, ``When it comes to the population of \ -Great Britain being invited by a multinational to wipe their bottoms \ -on what appears to be the work of a Knight of the Realm, then a last \ -stand must be taken.'' \ - \n\n\ -As reported by News of the Weird #491, 4-jul-1997. - -*hacks.sierpinski.documentation: \ -This draws the two-dimensional variant of the recursive Sierpinski \ -triangle fractal. Written by Desmond Daignault. - -*hacks.braid.documentation: \ -Draws random color-cycling inter-braided concentric circles. Written \ -by John Neil. - -*hacks.galaxy.documentation: \ -This draws spinning galaxies, which then collide and scatter their \ -stars to the, uh, four winds or something. Originally an Amiga \ -program by Uli Siegmund. - -*hacks.bouboule.documentation: \ -This draws what looks like a spinning, deforming baloon with \ -varying-sized spots painted on its invisible surface. Written by \ -Jeremie Petit. - -*hacks.swirl.documentation: \ -More flowing, swirly patterns. This version is by M. Dobie and R. \ -Taylor, but you might have seen a Mac program similar to this called \ -FlowFazer. There is also a cool Java applet of a similar concept - -*hacks.flag.documentation: \ -This draws a waving colored flag, that undulates its way around the \ -screen. The trick is the flag can contain arbitrary text and images. \ -By default, it displays either the current system name and OS \ -type, or a picture of ``Bob,'' but you can replace the text or the \ -image with a command-line option. Written by Charles Vidal and Jamie \ -Zawinski. - -*hacks.sphere.documentation: \ -Another of the classic screenhacks of the distant past, this one \ -draws shaded spheres in multiple colors. This hack traces its \ -lineage back to Tom Duff in 1982. - -*hacks.forest.documentation: \ -This draws fractal trees. Written by Peter Baumung. Everybody loves \ -fractals, right? - -*hacks.lisa.documentation: \ -This draws Lisajous loops, by Caleb Cullen. Remember that device \ -they had the Phantom Zone prisoners in during their trial in \ -Superman? I think that was one of these. - -*hacks.lissie.documentation: \ -Another Lissajous figure. This one draws the progress of circular \ -shapes along a path. Written by Alexander Jolk. - -*hacks.goop.documentation: \ -This draws set of animating, transparent, amoeba-like blobs. The \ -blobs change shape as they wander around the screen, and they are \ -translucent, so you can see the lower blobs through the higher ones, \ -and when one passes over another, their colors merge. Written by \ -Jamie Zawinski. I got the idea for this from a cool mouse pad I \ -have, which achieves the same kind of effect in real life by having \ -several layers plastic with colored oil between them. Written by \ -Jamie Zawinski. - -*hacks.starfish.documentation: \ -This generates a sequence of undulating, throbbing, star-like \ -patterns which pulsate, rotate, and turn inside out. Another display \ -mode uses these shapes to lay down a field of colors, which are then \ -cycled. The motion is very organic. Written by Jamie Zawinski. - -*hacks.munch.documentation: \n\ - DATAI 2 \n\ - ADDB 1,2 \n\ - ROTC 2,-22 \n\ - XOR 1,2 \n\ - JRST .-4 \n\ - \n\ -As reported by HAKMEM, in 1962, Jackson Wright wrote the above PDP-1 \ -code. That code still lives on in this screenhack, some 35 years \ -later. The number of lines of enclosing code has increased \ -substantially, however. This version is by Tim Showalter. - -*hacks.fadeplot.name: FadePlot -*hacks.fadeplot.documentation: \ -Draws what looks like a waving ribbon following a sinusoidal path. \ -Written by Bas van Gaalen and Charles Vidal. - -*hacks.coral.documentation: \ -Simulates coral growth, albeit somewhat slowly. This image doesn't \ -really do it justice. Written by Frederick Roeber. - -*hacks.mountain.documentation: \ -Generates random 3d plots that look vaguely mountainous. Written by \ -Pascal Pensa. - -*hacks.triangle.documentation: \ -Generates random mountain ranges using iterative subdivision of \ -triangles. Written by Tobias Gloth. - -*hacks.worm.documentation: \ -An ancient xlock hack that draws multicolored worms that crawl around \ -the screen. Written by Brad Taylor, Dave Lemke, Boris Putanec, and \ -Henrik Theiling. - -*hacks.rotor.documentation: \ -Another ancient xlock demo, this one by Tom Lawrence. It draws a \ -line segment moving along a complex spiraling curve. I tweaked this \ -to generate curvier lines, but still frames of it don't look like \ -much. - -*hacks.ant.documentation: \ -A cellular automaton that is really a two-dimensional Turing machine: \ -as the heads (``ants'') walk along the screen, they change pixel \ -values in their path. Then, as they pass over changed pixels, their \ -behavior is influenced. Written by David Bagley. - -*hacks.demon.documentation: \ -A cellular automaton that starts with a random field, and organizes \ -it into stripes and spirals. Written by David Bagley. - -*hacks.loop.documentation: \ -This one produces loop-shaped colonies that spawn, age, and \ -eventually die. Written by David Bagley. - -*hacks.vines.documentation: \ -This one generates a continuous sequence of small, curvy geometric \ -patterns. It scatters them around your screen until it fills up, \ -then it clears the screen and starts over. Written by Tracy Camp and \ -David Hansen. - -*hacks.kaleidescope.documentation: \ -Another clone of an ancient meme, consisting largely of frenetic \ -rotational motion of colored lines. This one is by Ron Tapia. The \ -motion is nice, but I think it needs more solids, or perhaps just \ -brighter colors. More variations in the rotational speed might help, \ -too. - -*hacks.xjack.documentation: \ -This program behaves schizophrenically and makes a lot of typos. \ -Written by Jamie Zawinski. If you haven't seen Stanley Kubrick's \ -masterpiece, ``The Shining,'' you won't get it. Those who have \ -describe this hack as ``inspired.'' - -*hacks.xlyap.documentation: \ -This generates pretty fractal pictures by doing funky math involving \ -the ``Lyapunov exponent.'' It has a cool interactive mode, too. \ -Written by Ron Record. - -*hacks.cynosure.documentation: \ -A hack similar to `greynetic', but less frenetic. The first \ -implementation was by Stephen Linhart; then Ozymandias G. Desiderata \ -wrote a Java applet clone. That clone was discovered by Jamie \ -Zawinski, and ported to C for inclusion here. - -*hacks.flow.documentation: \ -Another series of strange attractors: a flowing series of points, \ -making strange rotational shapes. Written by Jeff Butterworth. - -*hacks.epicycle.documentation: \ -This program draws the path traced out by a point on the edge of a \ -circle. That circle rotates around a point on the rim of another \ -circle, and so on, several times. These were the basis for the \ -pre-heliocentric model of planetary motion. Written by James \ -Youngman. - -*hacks.interference.documentation: \ -Another color-field hack, this one works by computing decaying \ -sinusoidal waves, and allowing them to interfere with each other as \ -their origins move. Written by Hannu Mallat. - -*hacks.truchet.documentation: \ -This draws line- and arc-based Truchet patterns that tile the screen. \ -Written by Adrian Likins. - -*hacks.bsod.name: BSOD -*hacks.bsod.documentation: \ -BSOD stands for ``Blue Screen of Death.'' The finest in personal \ -computer emulation, this hack simulates popular screen savers from a \ -number of less robust operating systems. Written by Jamie Zawinski. - -*hacks.crystal.documentation: \ -Moving polygons, similar to a kaleidescope (more like a kaleidescope \ -than the hack called `kaleid,' actually.) This one by Jouk Jansen. - -*hacks.discrete.documentation: \ -More ``discrete map'' systems, including new variants of Hopalong and \ -Julia, and a few others. Written by Tim Auckland. - -*hacks.kumppa.documentation: \ -Spiraling, spinning, and very, very fast splashes of color rush \ -toward the screen. Written by Teemu Suutari. - -*hacks.rd-bomb.name: RD-Bomb -*hacks.rd-bomb.documentation: \ -Another variation of the `Bomb' program by Scott Draves. This draws \ -a grid of growing square-like shapes that, once they overtake each \ -other, react in unpredictable ways. ``RD'' stands for \ -reaction-diffusion. - -*hacks.sonar.documentation: \ -This program draws a simulation of a sonar screen. Written by \ -default, it displays a random assortment of ``bogies'' on the screen, \ -but if compiled properly, it can ping (pun intended) your local \ -network, and actually plot the proximity of the other hosts on your \ -network to you. It would be easy to make it monitor other sources of \ -data, too. (Processes? Active network connections? CPU usage per \ -user?) Written by Stephen Martin. - -*hacks.t3d.name: T3D -*hacks.t3d.documentation: \ -This draws a working analog clock composed of floating, throbbing \ -bubbles. Written by Bernd Paysan. - -*hacks.penetrate.documentation: \ -This hack simulates the classic arcade game Missile Command. Written \ -by Adam Miller. - -*hacks.deluxe.documentation: \ -This draws a pulsing sequence of stars, circles, and lines. It would \ -look better if it was faster, but as far as I can tell, there is no \ -way to make this be both: fast, and flicker-free. Yet another reason \ -X sucks. Written by Jamie Zawinski. - -*hacks.compass.documentation: \ -This draws a compass, with all elements spinning about randomly, for \ -that ``lost and nauseous'' feeling. Written by Jamie Zawinski. - -*hacks.squiral.documentation: \ -Draws a set of interacting, square-spiral-producing automata. The \ -spirals grow outward until they hit something, then they go around \ -it. Written by Jeff Epler. - -*hacks.xflame.documentation: \ -Draws a simulation of pulsing fire. It can also take an arbitrary \ -image and set it on fire too. Written by Carsten Haitzler, hacked on \ -by many others. - -*hacks.wander.documentation: \ -Draws a colorful random-walk, in various forms. Written by Rick \ -Campbell. - -*hacks.critical.documentation: \ -Draws a system of self-organizing lines. It starts out as random \ -squiggles, but after a few iterations, order begins to appear. \ -Written by Martin Pool. - -*hacks.phosphor.documentation: \ -Draws a simulation of an old terminal, with large pixels and \ -long-sustain phosphor. It can run any program as a source of the text \ -it displays. Written by Jamie Zawinski. - -*hacks.xmatrix.documentation: \ -A rendition of the text scrolls seen in the movie ``The Matrix.'' \ -Written by Jamie Zawinski. - -*hacks.petri.documentation: \ -This simulates colonies of mold growing in a petri dish. Growing \ -colored circles overlap and leave spiral interference in their wake. \ -Written by Dan Bornstein. - -*hacks.shadebobs.name: ShadeBobs -*hacks.shadebobs.documentation: \ -This draws smoothly-shaded oscilating oval patterns, that look \ -something like vapor trails or neon tubes. Written by Shane Smit. - -*hacks.ccurve.name: C Curve -*hacks.ccurve.documentation: \ -Generates self-similar linear fractals, including the classic ``C \ -Curve.'' Written by Rick Campbell. - -*hacks.blaster.documentation: \ -Draws a simulation of flying space-combat robots (cleverly disguised \ -as colored circles) doing battle in front of a moving star field. \ -Written by Jonathan Lin. - -*hacks.bumps.documentation: \ -A bit like `Spotlight', except that instead of merely exposing part \ -of your desktop, it creates a bump map from it. Basically, it \ -3D-izes a roaming section of your desktop, based on color intensity. \ -Written by Shane Smit. - -*hacks.xteevee.name: XTeeVee -*hacks.xteevee.documentation: \ -XTeeVee simulates various television problems, including static, \ -loss of vertical hold, and a test pattern. By Greg Knauss. - -*hacks.xspirograph.name: XSpiroGraph -*hacks.xspirograph.documentation: \ -Simulates that pen-in-nested-plastic-gears toy from your childhood. \ -By Rohit Singh. - -*hacks.webcollage.name: WebCollage -*hacks.webcollage.documentation: \ -This program makes collages out of random images pulled off of the \ -World Wide Web. It finds these images by doing random web searches, \ -and then extracting images from the returned pages. It can also be \ -set up to filter the images through the `VidWhacker' program, above, \ -which looks really great. \ - \n\n\ -(Note that most of the images it finds are text, and not pictures. \ -This is because most of the web is pictures of text. Which is pretty \ -sad.) Written by Jamie Zawinski. - -*hacks.vidwhacker.name: VidWhacker -*hacks.vidwhacker.documentation: \ -This is actually just a shell script that grabs a frame of video from \ -the system's video input, and then uses some PBM filters (chosen at \ -random) to manipulate and recombine the video frame in various ways \ -(edge detection, subtracting the image from a rotated version of \ -itself, etc.) Then it displays that image for a few seconds, and \ -does it again. This works really well if you just feed broadcast \ -television into it. \ - \n\n\ -Currently, the three lines of the script that actually grab the \ -source picture are SGI specific, but it should be trivial to adapt it \ -to work on other systems that can grab video (please send me the \ -changes if you do this...) - -*hacks.rocks.documentation: \ -This draws an animation of flight through an asteroid field, with \ -changes in rotation and direction. It can also display 3D \ -separations for red/blue glasses! Mostly written by Jamie Zawinski. - -*hacks.bubbles.documentation: \ -This simulates the kind of bubble formation that happens when water \ -boils:small bubbles appear, and as they get closer to each other, \ -they combine to form larger bubbles, which eventually pop. Written \ -by James Macnicol. - -*hacks.gears.documentation: \ -This draws a set of turning, interlocking gears, rotating in three \ -dimensions. Another GL hack, by Danny Sung, Brian Paul, and Ed \ -Mackey. - -*hacks.superquadrics.documentation: \ -Ed Mackey reports that he wrote the first version of this program in \ -BASIC on a Commodore 64 in 1987, as a 320x200 black and white \ -wireframe.

It has the \ -same shiny-plastic feel as Superquadrics, as many computer-generated \ -objects do... - -*hacks.cage.documentation: \ -This draws Escher's ``Impossible Cage,'' a 3d analog of a moebius \ -strip, and rotates it in three dimensions. Written by Marcelo \ -Vianna. - -*hacks.moebius.documentation: \ -Another M. C. Escher hack by Marcelo Vianna, this one draws \ -``Moebius Strip II,'' a GL image of ants walking along the surface of \ -a moebius strip. - -*hacks.stairs.documentation: \ -by Marcelo Vianna's third Escher GL hack, this one draws an \ -``infinite'' staircase. - -*hacks.pipes.documentation: \ -If you've ever been in the same room with a Windows NT machine, \ -you've probably seen this GL hack. This version is by Marcelo \ -Vianna. - -*hacks.sproingies.documentation: \ -Q-Bert meets Marble Madness! Written by Ed Mackey. - -*hacks.rubik.documentation: \ -Draws a Rubik's Cube that rotates in three dimensions and repeatedly \ -shuffles and solves itself. Another fine GL hack by Marcelo Vianna. - -*hacks.atlantis.documentation: \ -This is xfishtank writ large: a GL animation of a number of sharks, \ -dolphins, and whales. The swimming motions are great. Originally \ -written by Mark Kilgard. - -*hacks.lament.documentation: \ -Animates a simulation of Lemarchand's Box, repeatedly solving itself. \ -Requires OpenGL, and a machine with fast hardware support for texture \ -maps.
