I like this one, from 1 year ago; a tall structure rendered in Blender: https://www.youtube.com/watch?v=D50iRzBI3qc

Yeah I helped build a 3D parametric engine a few years back at my company. This kind of stacked game of life was one of the first script I added to test it, alongside the 3D terrain generation using Perlin noise.

I highly doubt I was the first one (and I mean that was 4 years ago so the one from 2018 definitely precedes it), however it had a bunch of extra features like colors associated with the initial states and the colors would also propagate and merge alongside the cells

That 3D printed one is amazing!
