ABCnews has a story linking Ginger to a patent filed by the inventor. According to ABC, Ginger is likely a personal, single-wheel scooter. This actually makes a lot of sense considering that the guy also invented that incredible gyroscopic wheelchair that can stand on two wheels and climb stairs. I don't know how fast I'd want to go on one of those things, probably not more than 15 or 20mph, but it looks pretty nifty.
