NAME
quasicrystal - aperiodic plane tilings.
SYNOPSIS
quasicrystal [-display host:display.screen] [-visual visual] [-window]
[-root] [-delay number] [-speed number] [-count number] [-contrast per-
cent] [-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.
-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.
