Sketch-A-Move
Another gem from T&T. I'm surprised I haven't come across more toy technology working in his way (Sketch-a-Move was developed back in 2004 and 2006).
From WMMNA:
"Players can draw on the top of the car the tracks that the toy will have to follow.
For example, if you draw a circle on the toy car, it will move in a circle. If you draw a complicated spiral, the car will move in a spiral.
On top of the toy is a screen made from an analog editable material. Under it, a touch screen allows the stylus like input to be translated into movement by a microprocessor. The movement is performed by 2 solenoids to steer the car and a motor to give the speed."
