Not much to the article, so I guess the interesting part is the actual game: https://scratch.mit.edu/projects/164407978/#fullscreen

> It’s a slightly unusual implementation in that the surface of the game is, in effect, spherical – i.e. the edges are effectively a feature of the projection of the surface but left joins to right, top to bottom and so on.

I believe that is a torus, and not at all an unusual implementation choice for the Game of Life.
