Chipmunk (Chipmunk2D) is a lightweight 2D rigid-body physics engine written in C. It simulates collisions and motion by adding bodies, shapes, and joints (constraints) to a space and advancing time every frame, and speeds up collision checks with spatial hashing. It has been used in game engines such as Cocos2d and is often used with Pygame through Pymunk, its Python binding.
