I’ve done this before in Blender but always wanted to use the simulation zone to model the cellular automata. Once the initial pattern is created each subsequent pattern is generated based on the previous pattern. It’s way easier to understand if you read the wiki article first.
Wikipedia article on Conway’s Game of Life
The output pattern of each generation is rendered as small spheres for dead cells, larger ones for the living.
The Blend file is available on Gumroad for free.
