Generates random 3D plots that look vaguely mountainous. Written by Pascal Pensa; 1997.

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. https://en.wikipedia.org/wiki/Moire_pattern Written by Jamie Zawinski; 1998.

When the lines on the screen Make more lines in between, That's a moire'! https://en.wikipedia.org/wiki/Moire_pattern Written by Jamie Zawinski and Michael Bayne; 1997.

Scrolls a dump of its own memory in three windows at three different rates. Written by Jamie Zawinski; 2004.

Generates random mazes, with three different algorithms: Kruskal, Prim, and a depth-first recursive backtracker. It also solves them. Backtracking and look-ahead paths are displayed in different colors. https://en.wikipedia.org/wiki/Maze_generation_algorithm https://en.wikipedia.org/wiki/Maze_solving_algorithm Written by Martin Weiss, Dave Lemke, Jim Randell, Jamie Zawinski, Johannes Keukelaar, and Zack Weinberg; 1985.

A cellular automaton that generates loop-shaped colonies that spawn, age, and eventually die. https://en.wikipedia.org/wiki/Langton%27s_loops Written by David Bagley; 1999.

repairs burn-in on LCD monitors. This saver is functional, rather than pretty. Believe it or not, screen burn is not a thing of the past. It can happen to LCD screens pretty easily, even in this modern age. However, leaving the screen on and displaying high contrast images can often repair the damage. That's what this screen saver does.

Spiraling, spinning, and very, very fast splashes of color rush toward the screen. Written by Teemu Suutari; 1998.

A simple kaleidoscope made of line segments. See "GLeidescope" for a more sophisticated take. https://en.wikipedia.org/wiki/Kaleidoscope Written by Ron Tapia; 1997.

A 3D immersion of of a Klein bottle that smoothly deforms between the Etruscan Venus surface, the Roman surface, the Boy surface, and the Ida surface. Topologically, all surfaces are Klein bottles, even the Roman and Boy surfaces, which are doubly covered and therefore appear to be an immersed real projective plane. You can walk on the Klein bottle or rotate it in 3D. Since all the surfaces except the Ida surfaces have points where the surface normal is not well defined for some points, walking is performed on the Ida surface. Furthermore, it is possible to smoothly deform the surface between the Etruscan Venus surface, the Roman surface, the Boy surface, and the Ida surface surface while turning it. Inspired by George K. Francis's book "A Topological Picturebook", Springer, 1987, George K. Francis's paper "The Etruscan Venus" in P. Concus, R. Finn, and D. A. Hoffman: "Geometric Analysis and Computer Graphics", Springer, 1991, and a video entitled "The Etruscan Venus" by Donna J. Cox, George K. Francis, and Raymond L. Idaszak, presented at SIGGRAPH 1989. https://en.wikipedia.org/wiki/Boy%27s_surface https://en.wikipedia.org/wiki/Roman_surface https://en.wikipedia.org/wiki/Klein_bottle http://mathworld.wolfram.com/BoySurface.html http://mathworld.wolfram.com/RomanSurface.html http://mathworld.wolfram.com/EtruscanVenusSurface.html http://mathworld.wolfram.com/IdaSurface.html Written by Carsten Steger; 2020.
