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. + +Ported from the code by j.tarbell at http://complexification.net +.SH OPTIONS +.I substrate +accepts the following options: +.TP 8 +.B \-wireframe (Default: \fIFalse\fP) +Don't draw sand-painting colored effects, only make a wireframe. +.TP 8 +.B \-max\-cycles \fIcyclecount\fP (Default: \fI10000\fP) +Maximum number of growth cycles before restarting.
