So i made a dice simulation app called Awesome Dice 3D (yes, that is the best name in the world) and i have released the source code if anyone wants to poke around with it, or maybe for people that are trying to learn how to use bullet physics (like i was when making the app) it could be nice to see some basic physics in a complete project.
