Canesta
Jennifer Bove, a former Interaction-Ivrea student, sent me a link to a case study on a gestural entertainment center that she and a team at Kicker Studio developed for camera maker Canesta:

Canesta, Inc. is the inventor of revolutionary, low-cost electronic perception technology that enables ordinary electronic devices in consumer, security, industrial, medical, automotive, factory automation, gaming, military, and many other applications to perceive and react to objects or individuals in real time.

In Fall 2008, Canesta approached Kicker Studio to create a demonstration of their latest camera technology for the Consumer Electronics Show 2009 and at the TV of Tomorrow conference. The prototype was to be of an entertainment center controlled by gestures alone, and powered, of course, by a Canesta camera.

This highly attractive project is well reported in a case study full of photos and videos. It is a recommended read.
