+This program draws a simple orbital simulation. If you turn on \

+"*hacks.qix.documentation: \
+This is the swiss army chainsaw of qix programs. It bounces a series \
+of line segments around the screen, and uses variations on this basic \

+by Jamie Zawinski.",
+"*hacks.attraction.documentation: \
+Like qix, this uses a simple simple motion model to generate many \
+different display modes. The control points attract each other up to \
+a certain distance, and then begin to repel each other. The \
+attraction/repulsion is proportional to the distance between any two \
+particles, similar to the strong and weak nuclear forces. \
+ \\n\\n\
+One of the most interesting ways to watch this hack is simply as \
+bouncing balls, because their motions and interactions with each \
+other are so odd. Sometimes two balls will get into a tight orbit \
+around each other, to be interrupted later by a third, or by the edge \
+of the screen. It looks quite chaotic. \

+on some ancient PDP-11 code.",
+"*hacks.rorschach.documentation: \
+This generates random inkblot patterns. The algorithm is deceptively \
+simple for how well it works; it merely walks a dot around the screen \

+are your own problem. Written by Jamie Zawinski.",

+"*hacks.imsmap.name: IMSmap",
+"*hacks.imsmap.documentation: \
+This generates random cloud-like patterns. It looks quite different \
+in monochrome and color. The basic idea is to take four points on \
+the edge of the image, and assign each a random ``elevation''. Then \
+find the point between them, and give it a value which is the average \
+of the other four, plus some small random offset. 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. \

+"*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 \

+colorful visible. Warning, if the effect continues after the screen \
+saver is off, seek medical attention. Written by David Wald and \
+Vivek Khera. \

+A number of these screenhacks have the ability to take an image of \

+when you feed it an external video signal instead of letting it grab \

+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. \

+"*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.",

+It generates a random maze, then solves it with visual feedback. \

+"*hacks.noseguy.documentation: \
+A little man with a big nose wanders around your screen saying \

+"*hacks.moire.documentation: \
+This one draws cool circular interference patterns. Most of the \

+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 \

+In April 1997, Sir Roger Penrose, a British math professor who has \

+Corporation, which Penrose said copied a pattern he created (a \

+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 \

+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 \

+Written by Adrian Likins.",
+"*hacks.bsod.name: BSOD",

+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.",

+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.",

+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 \

+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.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.",
