Oh yes. The creator of WiiMedia and professor of interaction technology – Akihiko Shirai – quickly whipped our programmers into shape with Processing and let them loose with the Wiimotes.
He divided them into small teams of three to four students (each given a specific role) and – in just three short days – we saw them produce a pancake-frying simulation, darts, horse racing, space shooters, a classic artillery game and more.
The “winning” team (by votes among all participants) created a dueling game of spellcasting in a classic western setting, and were awarded Prof. Shirai’s personal blue Wiimote. 🙂

Akihiko sent me a link to his presentation slides at Siggraph Asia 2009. Lot’s of pictures from GAME in there. 🙂
