Inspired at an early age by Piccadilly Circus, I concentrated on mastering various useful abilities.
Here's some documentary evidence that I can juggle - an avi movie (152kB) compressed with Indeo 5. Some good hints to get you started may be found at the Juggling Information Service and (for riding those funny one-wheeled contraptions) at The Unicycle Page.
My current goals are to juggle 5 balls at once, and to be able to remain stationary on the unicycle. (Information for non-unicyclists: moving forward is easy, backwards is harder, and staying still is hardest.)
As I have no human-sized cannon, I'm afraid my plans to shoot myself over my single-storey house have been postponed indefinitely.
