Got Processing? Then try out Nakul Rao’s Pong program. He has posted code for both a single player and two player version. He also had sketched for Pong_art versions which provide visual variations on the game.
You can find the project code on GitHub.
(NOTE: If you get an error when running this sketch regarding a missing file named “AgencyFB-Reg-48.vlw”, you can download the file from GitHub. Just copy it into the Processing sketch’s folder.)
