Cellular automata posses a particular beauty, that lies between their viral spreading behavior and their lo-fi/glitching aesthetics.
In this sketch life-like automata are constrained in a predetermined shape, another shape determines the boundary of initlialization seeds. You can choose one of four shapes with the console and activate automatic reset of the automaton (each 10 frames). Another set of checkbox in the console let you choose the automaton rules of birth and survival. The checkbox to the right of the rules activate the "wrong mode" in which the automaton is updated as che cell are scanned without using another array to store the results, this create another whole set of simulated biology visuals.
