Golly (program)

Golly is a tool for the simulation of cellular automata. It is free open-source software written by Andrew Trevorrow and Tomas Rokicki;^[3] it can be scripted using Lua^[1] or Python. It includes a hashlife algorithm that can simulate the behavior of very large structured or repetitive patterns such as Paul Rendell's Life universal Turing machine,^[4] and that is fast enough to simulate some patterns for 2³² or more time units.^[5] It also includes a large library of predefined patterns in Conway's Game of Life and other rules.^[6]
