Powerball
I got a Powerball gyroscope toy and have been exercising with it, typically getting around 8,000 RPM but once momentarily breaking 10,000 RPM. I may yet write a piece about geeky forms of exercise.
The disturbing thing about the Powerball is of course that everyone who has seen it, starting with Aaron, has immediately asked "Is that meant to cause RSI, or cure it?".
