Tilmann Schlootz's Audi Snook.

Via Trendhunter:

"While we may laugh at this monowheel car concept by designer Tilmann Schlootz, it has actually won a Michelin Challenge Design Award 2008. It will also be showcased at the “Hannover Fair” from 21-25 April 2008.

How does it work? Tilmann Schlootz describes it as, “The Magic Egg of Columbus, or better, two billard balls standing on each other: this icon is my origin on the way of reducing the hardware demands of physical mobility to the minimum. One point touching the ground, the inverse pendulum in motion. Agility through instability, controlled by artificial intelligence - that is my formal issue.”
