Yes BitBlt magic is amazing. The code posted above runs with multiple frames per second even on SqueakJS.

I think I once made a Morph called LifeMorph, that used the BitBlt magic Tim mentioned. That was pretty fast 20 years ago.
I can't say I have the code handy, but I do find it mentioned here for example.

Very cool. I would not volunteer to refactor that :-D
It's tricky to get high performance GameOfLife in Squeak. Here is a morph I worked on. I use an array as data structure. Each cell is an integer. Neighbouring cells alive are 0 to 8 and alive cell are 10 + neighbours.
It gets a decent framerate.
Best, Karl

A fabulous example of Turing completeness and by far the most sophisticated Life system I’ve seen. https://woodrush.github.io/blog/posts/2022-01-12-lisp-in-life.html
