AUTOMATON*
Chaos
This uses the Moore neighbourhood & the maximum of 256 cell states. The
states are partitioned into two sections. On one, evolution occurs by
averaging & incrementing the cells (as in Rug) & on the other in a
'approximately' chaotic manner; there is a slight overlap between the two
resulting bands of states. This leads to competing regions of 'Rug' type
stability & of 'Chaos'. Try 150x100 & 50x40 windows.
