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.
22
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
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.
