Trevor Blackwell who had built a few (ver 1, ver 2) segway clones but felt that 2 wheels was 1 too many. So he built a one wheeled electric unicycle! His site has full parts list and instructions on how to build your own.

“The unicycle balances itself using a simple feedback loop between a solid-state gyroscope and the wheel motor. When it detects itself tilting forward, it runs the wheel forward to keep it vertical. When it detects itself tilting backwards it runs the wheel backwards. It does this so rapidly (200 updates per second) that it feels perfectly smooth. This is really the same thing that a conventional unicycle rider does with his legs.”
