I just got a new piece of kit in the post today - a toy/exercise machine hybrid called a powerball.
Basically, it's a gyroscope set into a ball, and the aim of the game is to get it to rotate as fast as possible, while it produces pretty lights. It's also exercise though - the faster it gets, the harder it is (Apparantly at higher speeds it's the equivalent of moving 40kg).
It took me a while to get the hang of starting it, but it's fun
Plus, I can't feel my repetetive strain injury after playing with it.
The only bit that bugs me is that I can't get it to turn on the LCD (whilst not using it) without erasing my high score.
So, has anyone tried one of these things? And what did you think?
