Hey all, long time lurker here.
Saturation, our first (real) iPhone app, launched today. It's a simple app that allows users to play around with color themes supplied by Adobe Kuler using custom color visualizers. It was built with cocos2d, it is a free app and the source is also freely available.
Here are some screens:

I would like give a big "thank you" to riq and the rest of the cocos2d team for making such a great framework! I went through numerous framework rewrites on this, just playing around and figuring out how core animation, opengl, etc. work and in the end cocos2d was by far the best route to take.
Any feedback you all may have would be greatly appreciated.
