Hacked tyco rebound rc car, now I need ideas on what to do with it

Today I dug out one of my old childhood favorites, the tyco rebound. In case you've never seen one, the rebound has 4 wheels large enough so the car can flip itself over. Steering is done like a tank with no treads, each side going forward or backward. It's also FAST. I tore it open and it's built perfectly for modding. There are 6 wires attached to a circuit board. 2 for each motor and two coming from a 6 volt battery pack.

So far just a Stepper motor hooked up!
