Algodoo

I found out that I could add a second rotor to my single rotor spring engine to balance it out, and if I could make a functional 2-rotor, why not a 4-rotor, such as that which led the Mazda 787B to victory in the 1991 24 Hours of Le Mans race? If only Algodoo had sound, this engine would be even more spectacular (still kind of a work in progress anyway). Arrow keys to move and S to start the engine.
