Ripstik
The evolution of the skateboard is littered with false starts (remember the snakeboard?) but its latest incarnation may just be a winner. The two plates, which are more stable than they look, twist about the central shaft, allowing you to propel yourself along flats or even slight inclines once you've mastered the required wiggle. The casters swivel in all directions so you can change course in the blink of an eye.
