.SH DESCRIPTION
Lines like crystals grow on a computational substrate. A simple
perpendicular growth rule creates intricate city-like structures. Optionally, cracks may also be circular, producing a cityscape more familiar to places for which city planning is a distant, theoretical concern.
Number of sand grains dropped during coloring. More grains cause
a denser colour but use more cpu power.
