I was discussing with my supervisor yesterday the experimentation booth that is being built as the central feature of the lab that he is putting together (and the reason for the existence of his flock of grad students).

It's a pretty nice setup, including vibration-damping floor, acoustically shielded walls, large-screen rear-projection display, surround-sound (in the sense of speakers all over the place), and a motion tracking system that could, for instance, track the exact location of your ears.

He concluded by mentioning that it will be a great place to watch DVDs.
