The Toronto NSCoder group is running a book club for Learning Cocos2D by Rod Strougo and Ray Wenderlich. I'm a cocos2d n00b myself, but I figured I would put a spin on things and learn the C++ based cocos2d-x while following along with the book.
I'll post code from my projects (probably one per chapter) here. Follow along, fork, send pull requests, etc.
