Algodoo

A completly modular collision engine. Its rotary deisgn utilizes sets of Reuleaux Triangles with a collider at the meeting point of 3 rotors. The space between the rotors expands and contracts because the rotors are surfaces of constant width (although this probably works with any shape and its "mirror", a shape thet works with the original like a gear). The engine is not fast at all, but it does produce large amounts of torque. How much torque, exactly, I need someone to figure out. Drag the flywheel any direction to start the engine.
