Looki say he could make a port of Box2D for iOS if he can buy a Mac, licence and a iOS device + some money for the effort. How much interest is there here for something like this? The Box2D extension would be unvaluable in my eyes to have and it feels like its made for iOS (just look at Angry Birds).
So how many people would be interested to pitch in for something like this? We would need to gather about 3000 to make it happen.
If you for some reason dont know what Box2D is :P
