DESCRIPTION

15       A quasicrystal is a structure that is ordered but  aperiodic.   Two-di‐
16       mensional  quasicrystals  can  be  generated  by adding a set of planes
17       where x is the sine of y. Different complex aperiodic plane tilings are
18       produced  depending on the period, position, and rotation of the compo‐
19       nent planes, and whether the rotation of the planes is evenly  distrib‐
20       uted  around  the circle (the "symmetric" option, above) or random. See
21       also the "RD-Bomb", "CWaves" and "Penrose" screen savers.

OPTIONS

24       --visual visual
25               Specify which visual to use.  Legal values are the  name  of  a
26               visual  class,  or the id number (decimal or hex) of a specific
27               visual.
28
29       --window
30               Draw on a newly-created window.  This is the default.
31
32       --root  Draw on the root window.
33
34       --window-id number
35               Draw on the specified window.
36
37       --delay number
38               Per-frame delay, in microseconds.  Default:  30000  (0.03  sec‐
39               onds.).
40
41       --speed number
42               Animation speed. 2 for twice as fast, 0.5 for half as fast.
43
44       --contrast contrast
45               Contrast. Sort of.  Default 30%.
46
47       --count number
48               How many planes to use. Default 17.
49
50       --wander | --no-wander
51               Whether the planes should displace horizontally and vertically.
52
53       --spin | --no-spin
54               Whether the planes should rotate.
55
56       --asymmetric
57               Allow  each plane to rotate freely instead of being constrained
58               to an even distribution around the circle.
59
60       --fps | --no-fps
61               Whether to show a frames-per-second display at  the  bottom  of
62               the screen.
63

ENVIRONMENT

65       DISPLAY to get the default host and display number.
66
67       XENVIRONMENT
68               to  get  the  name of a resource file that overrides the global
69               resources stored in the RESOURCE_MANAGER property.
70
71       XSCREENSAVER_WINDOW
72               The window ID to use with --root.
