Who came up with this crazy but cool electric monowheel?

One look at this circular contraption, and your first thought might be, "What is this wacky wheel?" Your next question could be, "Who came up with this crazy concept?" 

Well, it's called a monowheel, and Make It Extreme is behind the massive circular thingamajig with a rider perched inside like some futuristic hamster.

These folks have taken their gas-guzzling monowheel and given it an eco-friendly makeover. The result? A ground-up, all-electric redesign that's pushing the envelope of personal transportation.
