Iphone App Rag Doll (1841738)

I have a simple iPhone project that consists in making a Ragdoll falling like the attached example.... With random objects in the way with in a infinite falling. This app also should have a functionality that allows the user to use the iPhone photos to change the doll face and the users should have the option to crop the photo before uses it in the rag doll as well. The rag doll falling part is basically a translation of the source code in actionscript to objective C... All the physics are done. I have all the wireframes and design for the app, and I will show it for the winner.
