Riding the One Wheel
BBC Click's Spencer Kelly takes a ride to the Consumer Electronics Show in Las Vegas on a One Wheel - a cross between a skateboard and a unicycle. It is electrically powered and can move you at 12 mph and travel up to six miles (9km) before it needs recharging.
Innovation is the name of the game at CES 2014 but which ideas will turn into big success stories? Spencer also looks at some of the new ideas at this year's show.
