IOCCC29 winner: Pong game recompiles its own source code every frame, generated by a custom compiler

Summary

Jonah Uellenberg won the Ping Pong Prize at the 29th International Obfuscated C Code Contest (IOCCC29) with a version of Pong that recompiles its own source code on every frame. Each run prints the C source for the next frame with the game state embedded, so compiling and running that output advances the game by one step. Ironically, Uellenberg didn't write the obfuscated code directly; he created a custom programming language called Insert, wrote clean commented source in it, and used a custom compiler to generate the obfuscated C entry.
