[Eric] sent in this awesome job that he did as part of his graduation project. He built a game that utilizes a gyroscope as an input device. For the gyroscope, he’s utilizing a Powerball with a sensor inserted into it. This data is gathered by an Arduino in a quite enclosure. The whole system links to a PC through USB as well as is supposedly plug as well as play. There’s a video of the setup in action on the site, just try not to laugh as well difficult viewing them.
