I don't think I linked to it, mostly because the rest of the world did. There was this guy who made his own Segway like vehicle. Very very cool. Now, he's come up with a sequel, and since I haven't seen any other links to it, I will do so.

He's built a Segway style unicycle, you must take a look -- it's pretty damn cool. Especially the picture taken at what looks like the Burning Man festival.
