+[\-window]
+[\-root]
+[\-delay \fInumber\fP]
+[\-speed \fInumber\fP]

+[\-no-spin]
+[\-asymmetric]
+[\-fps]
+.SH DESCRIPTION
+A quasicrystal is a structure that is ordered but aperiodic.
+Two-dimensional 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 component
+planes, and whether the rotation of the planes is evenly distributed around
+the circle (the "symmetric" option, above) or random. See also the
+"RD-Bomb", "CWaves" and "Penrose" screen savers.
+.SH OPTIONS
+.TP 8
+.B \-visual \fIvisual\fP
+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.
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-delay \fInumber\fP
+Per-frame delay, in microseconds.  Default: 30000 (0.03 seconds.).
+.TP 8
+.B \-speed \fInumber\fP
+Animation speed. 2 for twice as fast, 0.5 for half as fast.
+.TP 8
+.B \-contrast \fIcontrast\fP
+Contrast. Sort of.  Default 30%.
+.TP 8
+.B \-count \fInumber\fP
+How many planes to use. Default 17.
+.TP 8
+.B \-wander | \-no-wander
+Whether the planes should displace horizontally and vertically.
+.TP 8
+.B \-spin | \-no-spin
+Whether the planes should rotate.
+.TP 8
+.B \-asymmetric
+Allow each plane to rotate freely instead of being constrained to an
+even distribution around the circle.
+.TP 8
+.B \-fps | \-no-fps
+Whether to show a frames-per-second display at the bottom of the screen.
+.SH ENVIRONMENT
+.PP
+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.
