Draws a randomly-colored Voronoi tessellation, and periodically zooms in and adds new points. The existing points also wander around. There are a set of control points on the plane, each at the center of a colored cell. Every pixel within that cell is closer to that cell's control point than to any other control point. That is what determines the cell's shapes. http://en.wikipedia.org/wiki/Voronoi_diagram Written by Jamie Zawinski; 2007. 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; 1999. Draws quasiperiodic tilings; think of the implications on modern formica technology. 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."

Subtractive colors Subtractive colors (reflected light) Swampy coloration This does bad things with quasi-spherical objects. You have a tetrahedron with tesselated faces. The vertices on these faces have forces on them: one proportional to the distance from the surface of a sphere; and one proportional to the distance from the neighbors. They also have inertia. The resulting effect can range from a shape that does nothing, to a frenetic polygon storm. Somewhere in between there it usually manifests as a blob that jiggles in a kind of disturbing manner. Written by Keith Macleod; 2003. This draws Escher's "Impossible Cage", a 3d analog of a moebius strip, and rotates it in three dimensions. http://en.wikipedia.org/wiki/Maurits_Cornelis_Escher Written by Marcelo Vianna; 1998. This draws a box and a few line segments, and generates a radial blur outward from it. This creates flowing field effects. This is done by rendering the scene into a small texture, then repeatedly rendering increasingly-enlarged and increasingly-transparent versions of that texture onto the frame buffer. As such, it's quite GPU-intensive: if you don't have a very good graphics card, it will hurt your machine bad. Written by Jamie Zawinski; 2002. This draws a pop-art-ish looking grid of pulsing colors. Written by Levi Burton; 2003.

This draws iterations to strange attractors: it's a colorful, unpredictably-animating swarm of dots that swoops and twists around. http://en.wikipedia.org/wiki/Attractor#Strange_attractor Written by Massimino Pascal; 1997. This draws rippling interference patterns like splashing water, overlayed on the desktop or an image. Written by Tom Hammersley; 1999. 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. I got the idea for this from a mouse pad I had once, which achieved the same kind of effect in real life by having several layers of plastic with colored oil between them. Written by Jamie Zawinski; 1997. This generates a languidly-scrolling vertical field of sinusoidal colors. Written by Jamie Zawinski; 2007. 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; 1997. This generates random cloud-like patterns. The 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. Coloration is done based on elevation. Written by Juergen Nickelsen and Jamie Zawinski; 1992. This generates random mazes (with three different maze-generation algorithms), and then solves them. Backtracking and look-ahead paths are displayed in different colors. http://en.wikipedia.org/wiki/Maze_generation_algorithm Written by Martin Weiss, Dave Lemke, Jim Randell, Jamie Zawinski, Johannes Keukelaar, and Zack Weinberg; 1985. This screen saver was removed from the XScreenSaver distribution as of version 4.22. 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.

This screen saver was removed from the XScreenSaver distribution as of version 5.08. This draws a waving colored flag, that undulates its way around the screen. 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". Written by Charles Vidal and Jamie Zawinski; 1997. This screen saver was removed from the XScreenSaver distribution as of version 5.10. It has been replaced by the more general "Polytopes" screen saver, which can display this object as well as others. The Polytopes "120-cell" object corresponds to this one. Hyperball is to hypercube as dodecahedron is to cube: this displays a 2D projection of the sequence of 3D objects which are the projections of the 4D analog to the dodecahedron. Technically, it is a "120 cell polytope". http://en.wikipedia.org/wiki/Hypercube http://en.wikipedia.org/wiki/Regular_polytope Written by Joe Keane; 2000. This screen saver was removed from the XScreenSaver distribution as of version 5.10. It has been replaced by the more general "Polytopes" screen saver, which can display this object as well as others. 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. http://en.wikipedia.org/wiki/Hypercube http://en.wikipedia.org/wiki/Regular_polytope Written by Joe Keane, Fritz Mueller, and Jamie Zawinski; 1992. 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; 1999. This simulates the 1971 Pong home video game, as well as various artifacts from displaying it on a color TV set. In clock mode, the score keeps track of the current time. http://en.wikipedia.org/wiki/Pong Written by Jeremy English and Trevor Blackwell; 2003. This takes an image 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, Vivek Khera, Jamie Zawinski, and Vince Levey; 1993. This 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 it interject some splashes of color into the scene, or go into a spin cycle, or stretch the image like taffy. Written by Scott Draves and Jamie Zawinski; 1997.
