Cool videos: Zorbing, Magic Wheel

Above is a video of Zorbing, which is basically strapping yourself to the inside of an inflated sphere and rolling down a hill. Zorbing uses gravity and you do travel a certain distance, so it could be considered green transport. Below the fold is a large-wheel, skateboard, scooter-like vehicle called Magic Wheel, which is very green because it's human powered. The Magic Wheel looks as easy to ride as a scooter but does not require the use of your hands for balance the way a skateboard does.
