Life imitates Life

A while ago somebody created a simulation of Conway’s Game of Life inside a bigger version of the Game of Life. Now, YouTube user Phillip Bradbury has created a very simple — and aurally pleasing1 — video showing it in action.

Apparently this is made possible by the Outer Totalistic Cellular Automata Meta-Pixel (OTCAMP), a “two state programmable unit cell which allows Conway’s Life to simulate any outer totalistic rule. OTCAMP is a meta-cell which is also a meta-pixel. OTCAMP meta-pixels display evolving meta-patterns on-screen in meta-realtime.”

An outer totalistic rule is a rule for a cellular automaton which defines the transitions between cell states based on the total number of switched-on surrounding cells surrounding them. The Game of Life is one such rule.
