Nice!! I had a lot of fun with a project like this with some more generalized rulesets. This video got the most views: https://www.youtube.com/watch?v=EW9Q0qMc2Xc (just running 3d Brian's Brain) but I like this one the most, with a much more general ruleset: https://www.youtube.com/watch?v=SoJvS6GuM3c&t=90s

The code is here: https://github.com/heyitsguay/gol3d

I keep meaning to go back and create an automated ruleset explorer that looks for stable but non-oscillating and non-constant population counts. Maybe someday...

Looks cool, although when I run it the simulation always seems to halt after a couple dozen steps.

I wonder if the 3D version exhibits behaviors similar to the 2D version, including periodic patterns.

I also have to link my favorite pattern, XKCD's homage to John Conway: https://xkcd.com/2293/

Imagine. And all that work trying to derive physics from TWO dimensional finite automata.

I wonder how complex a simulator of the Game of Life 3D itself would be? https://news.ycombinator.com/item?id=39799755

Certain rules do, though the exact analog rule of Conway's Game of Life is a bit boring as i recall. In general it was a lot easier to find interesting behavior in Brian's Brain rulesets.
