[day 4] Anyone used a cellular automata engine? (jlai.lu)

Part 2 is basically running just the isolation rule from Conway's game of life until the world state stabilizes. I'm curious if anyone noticed this and used an existing cellular automata program or library to handle the computation.

Another approach could be to run an image convolution kernel in GIMP (or some other image manipulation program). Something like

[
 1, 1, 1
 1, 0, 1
 1, 1, 1
]

and then filter pixels based on ≥4 or <4

    I build a program that runs various species of automata in raylib and c++. I can send you a link if you like. While running, the species can be interchanged (meaning the rule set). I also added different random densities and a gradient option. Plus I colour coded each cell based on the age (dead alive transition) which is very interesting to see.
