16 Lines like crystals grow on a computational substrate. A simple
17 perpendicular growth rule creates intricate city-like structures.

22 accepts the following options:
24 .B \-wireframe (Default: \fIFalse\fP)
25 Don't draw sand-painting colored effects, only make a wireframe.
27 .B \-max\-cycles \fIcyclecount\fP (Default: \fI10000\fP)
28 Maximum number of growth cycles before restarting. The higher this is,
29 the more complex the art.
31 .B \-growth\-delay \fIdelayms\fP (Default: \fI18000\fP)
32 Delay in ms between growth cycles. More delay, slower (but smoother
33 and less CPU intensive)
36 .B \-initial\-cracks \fInuminitial\fP (Default: \fI3\fP)
37 Initial number of cracks in the substrate
39 .B \-max\-cracks \fInummax\fP (Default: \fI100\fP)
40 Maximum number of cracks in the substrate at a single time
42 .B \-sand\-grains \fInumgrains\fP (Default: \fI64\fP)
43 Number of sand grains dropped during coloring. More grains cause
44 a denser colour but use more cpu power.
49 to get the default host and display number.
52 to get the name of a resource file that overrides the global
53 resources stored in the RESOURCE_MANAGER property.
