This project was just some fun I had with an 8x8 LED matrix from Adafruit where I programmed a version of Conway's "Game of Life" that runs in Micropython and displays on the LED matrix. It was a bit tricky to get it working without much memory available on the circuitplayground chip, but it works! It can do gliders, blinkers, and toads pretty well.
And a video of it in action (you can skip the soldering parts if you want)
Here is the entire program, which is fairly compact.
