SYNOPSIS

9       quasicrystal  [-display host:display.screen] [-visual visual] [-window]
10       [-root] [-delay number] [-speed number] [-count number] [-contrast per‐
11       cent] [-no-wander] [-no-spin] [-asymmetric] [-fps]

DESCRIPTION

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

OPTIONS

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

ENVIRONMENT

60       DISPLAY to get the default host and display number.
61
62       XENVIRONMENT
63               to get the name of a resource file that  overrides  the  global
64               resources stored in the RESOURCE_MANAGER property.
