Chris Carlson explores the design space of a simple graphical ruleset in an excellent post on the Wolfram Blog (which spends most of its time advertising Mathematica but occasionally gives us gems like this).

He has discovered a system that resonates well with the human imagination, like Richard Dawkins' Biomorphs do.

He rounds it off with an awesome Picasso quote: "Forcing yourself to use restricted means is the sort of restraint that liberates invention. It obliges you to make a kind of progress that you can’t even imagine in advance."
