Simon Bugler has taken a Raspberry Pi, a Skywriter gesture-detection board and a RasPiO Inspiring circle and driver board and created this quite lovely Wheel of Fortune. By waving a hand over the Skywriter board, he can set the ‘Wheel’ going which is displayed on the circle. The software that he’s written even slows down the Wheel realistically as it comes to a stop. You can see a longer demo below and read the tutorial of how to make your own here.
