I'm working on a Pong clone written with Cocoa and OpenGL, hosted at github: http://github.com/mk12/Pong-Ultimate . Its mainly for myself to learn, but I actually want to make it a fun game with lots of features, like different game modes, as far as pong can stretch anyway. I'm focusing a lot on code correctness and good design, and making it a very polished application from the user's perspective. The OpenGL code is completely legacy free/forward compatible. I'm thinking I'll be able to reuse a lot of the code (and things I learn from it) in other 2d games. Anyone is welcome to help, on code or other things like art and sound.

You might want to remove the period after the link, it messes up the url.

Thanks, fixed it.
