 .SH DESCRIPTION
 Lines like crystals grow on a computational substrate.  A simple 
-perpendicular growth rule creates intricate city-like structures.
+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.
