Lego RC car
I've just stumbled on this picture from last year when I build a Lego RC car. It is motorized using the Lego Mindstorm 2.0 Brick and two motors. (one for steering and one for propulsion).
For the controller I simply used the Lego Mindstorm remote.
It only had one speed: darn slow. It didn't stopped the kid from playing with it for days.
