Automaton is an app that displays 8-bit binary cellular automata. For those notÂ familiarÂ with CA, itÂ is aÂ discrete model studied inÂ computability theory,Â mathematics,Â theoretical biologyÂ and microstructure modeling. It consists of a regular grid ofÂ cells, each in one of a finite number ofÂ states, "On" and "Off" for example. The grid can be in any finite number of dimensions. For each cell, a set of cells called itsÂ neighborhood (usually including the cell itself) is defined relative to the specified cell (wikipedia).
