"Uellenberg's program goes further than we had ever imagined. As with many other IOCCC entries, it contains a message in its own source listing. If you squint a bit, you can see a Pong screen in the whitespace – two paddles and a ball. Compile it and run it, and it takes a keystroke to move one of the paddles… then it reformats its own source code and outputs a new, slightly different version, showing the updated game screen. You play the game by repeatedly compiling the output from the previous run. Each run outputs the source code for the next game. The frames of the game are its own changing source code." https://www.theregister.com/a/5265981
