CA Worm digital design: The CA Worm is an expanding construction of a one-dimensional cellular automata. Each successive row of the automata is rotated and enlarged just slightly from the last. The result is a worm-like form, interestingly textured with a bitwise logic. CLICK anywhere above to change the CA rule set and restart the worm growth. figure a. some example rulesets from Wolfram's 8-bit cellular automata method (with initial random conditions). Cellular automata are discreet dynamical systems with simple construction but complex emergent behavior. This particular implementation of CA is based on Wolfram's 8-bit Class 4 CA, using ruleset 114. The bits lit on each successive line of the CA are based on the lit bits of the previous lines. A similar cellular automata exists as a continually evolving interactive ring..
