quasicrystal(6) XScreenSaver manual quasicrystal(6) NAME quasicrystal - aperiodic plane tilings. SYNOPSIS quasicrystal [--display host:display.screen] [--visual visual] [--win- dow] [--root] [--window-id number] [--delay number] [--speed number] [--count number] [--contrast percent] [--no-wander] [--no-spin] [--asymmetric] [--fps] DESCRIPTION A quasicrystal is a structure that is ordered but aperiodic. Two-di- mensional quasicrystals can be generated by adding a set of planes where x is the sine of y. Different complex aperiodic plane tilings are produced depending on the period, position, and rotation of the compo- nent planes, and whether the rotation of the planes is evenly distrib- uted around the circle (the "symmetric" option, above) or random. See also the "RD-Bomb", "CWaves" and "Penrose" screen savers. OPTIONS --visual visual Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual. --window Draw on a newly-created window. This is the default. --root Draw on the root window. --window-id number Draw on the specified window. --delay number Per-frame delay, in microseconds. Default: 30000 (0.03 sec- onds.). --speed number Animation speed. 2 for twice as fast, 0.5 for half as fast. --contrast contrast Contrast. Sort of. Default 30%. --count number How many planes to use. Default 17. --wander | --no-wander Whether the planes should displace horizontally and vertically. --spin | --no-spin Whether the planes should rotate. --asymmetric Allow each plane to rotate freely instead of being constrained to an even distribution around the circle. --fps | --no-fps Whether to show a frames-per-second display at the bottom of the screen. ENVIRONMENT DISPLAY to get the default host and display number. XENVIRONMENT to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property. XSCREENSAVER_WINDOW The window ID to use with --root. SEE ALSO X(1), xscreensaver(1) COPYRIGHT Copyright (C) 2013 by Jamie Zawinski.
