Sketch-a-Move by Anab Jain and Louise Klinker
Sketch-a-Move is a project by Anab Jain and Louise Klinker. They actually did this a few years ago. It’s a concept for a toy car that allows you to explore the unique relationships between small surface doodles and actual physical movements. If you draw a circle on the top of the toy car, it will move in a circle. If you draw a complicated spiral, the car will move in a spiral. They don’t explain how it actually works or could work, but it sure looks like fun.
