A unit cell is a subset (usually rectangular or square) of the Life plane that tiles over the plane, along with a fixed number of distinct patterns, with each tile assuming one of the patterns, such that it simulates a cellular automaton, possibly itself. A unit Life cell is a unit cell that simulates the Game of Life. To avoid single cells themselves being considered unit cells, the size of a unit cell must be greater than 1x1.
The first unit Life cell was constructed by David Bell in 1996.[1] It employs standard glider logic to determine whether or not a glider should be present. The two states differ by a single glider. In 2004, Jared Prince modified David Bell's unit Life cell to support two (and therefore multiple) layers of Life universes, coined "deep cell".[2]
More recently OTCA metapixel was constructed that simulates any Life-like cellular automaton.[3] Designed to run quickly in HashLife, it has the advantage of having two states that are clearly distinct when zoomed out.
