As a thanks to all who serve this community I'd like to start posting some 'how-tos' for cocos2d on my blog. The first one is a re-usable pie timer that inherits from CCNode. I'm sure this has been done before but I'm sure someone will find this useful:

I hope I posted this in the right place. I didn't see a place for examples.
