Jeff Cook makes handcrafted art from exotic woods overlaid with patterns generated by cellular automata. You can see his work in person at Chalk Los Angeles through July. From Jeff's Wolfrule site:
Wolfrule Art is based on patterns generated by an extremely primitive computing device, the cellular automaton, which, as postulated by Wolfram, may some day explain the basic principles of much of life and nature. These patterns are used in art constructions made from wood, a basic product of nature, producing art that uses computations to produce patterns that may form the basis of life itself. Both the background and the pattern are made from wood. The selection of contrasting woods, with variations in grain and color, provide a stark and striking exhibition of the geometric patterns computed by the cellular automaton…
