Grids of cells that change state each step according to simple rules based on their neighbors. John von Neumann and Stanisław Ulam studied them in the 1940s, and Conway's Game of Life (1970) made them famous.
In terms of the visual inspiration, a lot of that comes from a combination between early computer art, specifically, computer art focused on algorithms, like elementary cellular automata, which is one of the algorithms that drives the Bitframes system.

Piter suggested using a non-linear function for the coefficient of springs of this cellular automata. So it led to an unexpected result, and we saw unusual patterns emerging from these jumping particles.
