I'm struck by the vignette involving the table leg, in which Oliver describes it as feeling "unnatural" to pass his kinect-sensed leg through the virtual table leg, even though there was no obstruction in "real life." I believe this is a demonstration of fully-convincing immersion, and Oliver is sure to point out its implications for the uncanny valley. This is so exciting from the perspective of social/cognitive science, too. I'm floored.
