I've been playing around with this X-Wheel. It's been a blast of bundle of fun. what the X-wheel is like the Segway but just one wheel without the handle--but twice the fun. you just stand on one wheel its self-balanced electrical wheel--the fun effect is like hovering and flying. it takes about half an hour to learn and get yourself balanced on one wheel.
Check out my profile picture to see what it look like.
I have two of them so everyone can try it out.
