If you haven't seen those "Human Tetris" videos from Japan (or the U.S. game show equivalent Hole in the Wall), the concept centers around an approaching wall with a cutout that players can fit through if they strike and hold the right pose.

Tampa coin-op studio Titan 4 Games built Silhouette, a gesture-based video game based on that concept, using Softkinetic's 3D gesture recognition software platform iisu. The middleware uses a 3D depth sensing camera to translate players' movements into the game, posing an on-screen character to meet an incoming wall.

Titan 4 Games expects to launch "new products based on the iisu technology", presumably including Silhouette, in the first half of 2010.
