LifeMaker is a cellular automata program. Cellular automata (CA) can be thought of as mini-universes. The universe starts at some initial state and evolves according to a simple local rule. Conway's Game of Life is by far the best known CA. LifeMaker includes Conway's Life along with 32 other rules. Unlike most Life programs LifeMaker uses color, allows you to change the size of the "universe", and lets you create your own rules. Shareware. Shareware/freeware downloaded from the Internet. LifeLab and LAZlife, two very nice programs for Conway's "Life", which illustrates the concept of "emergent behavior", i.e. repetitive application of very simple rules to a simple system over a sufficiently large number of iterations often yields system behavior that is richer, more interersting, amd more complex that one might have predicited on the basis of the simplicity of the system and the rules.
