This is an android app about Life-like 2D cellular automata:
Duel of Life lets you define two life-like cellular automata that compete against each other in the struggle for survival. It is not a game, yet entertaining and fascinating to observe. Based on John Conway’s popular “Game of Life” principles, more than 260.000 different rulesets can be applied to both red and blue cells, many of them offering intriguing behaviour and visual appearance.
