Simon has programmed a Conway Checkers game in Processing (Java). The game is a math version of traditional checkers and was invented by John Conway (famous as the author of the Game of Life). Simon learned about Conway Checkers in a Numberphile video and decided to make a computer version. It’s available on GitHub to download: https://github.com/simon-tiger/conway-checkers
Simon also wrote the rules of the game on GitHub in the README: https://github.com/simon-tiger/conway-checkers/blob/master/README.md
