Bumper Cars
Create a simulation of the bumper car ride (Amusement Park), where the cars move continuously around within the bumper arena. Add two bumper cars inside the arena. In this animation, each car should be moving forward a small amount until it gets too close to another car or to the wall, then turn the car a quarter of a revolution clockwise (to get a different direction) and continue moving forward. Use a switch (Controls) to stop and start the ride. As long as the switch is on, the ride should continue.
