You’re correct in guessing it’s a Cocoa app, although I spent more time thinking about OpenGL than Cocoa to write it. But then, maybe that’s the point.

The code isn’t particularly clean; this was a learning-Cocoa, learning-OpenGL, messing-around project of mine. If you’re still curious, email me and I’ll send it to you, but it’s not really ready for general consumption. I’ve got a few ideas bouncing around in my head for better managing the animation and maybe using more interesting models. My plan is that either when I’ve finished the things I’d like to do, or when I lose interest, I’ll make it GPL, since I’m not really out to make money on it.

I am guessing this was done in Cocoa… Any chance at seeing the code?
