Welcome back, and I hope you enjoy this mess of a three-year project… It turns out backing up in a cellular automaton can be an insanely difficult problem. This started as a "play button" project, but turned into an obsession. I recently came to the conclusion that there's no long-term winning this game (it has been shown to be NP hard, so I don't feel that bad) but AGH it should be easier than it is!

Join me in this video as I dive through the much fabled Game of Life, take a hike through a very strange space, and organize a dinner party. It's going to be a great time.

Check out the second channel with bonus content and Q&A videos!
