Here's a video/costume rig that lets you watch yourself run around in the third person like you were in a video game. Apparently it's also necessary to wear a Rollerball outfit and spiked helmet while you do this in a public park on a sunny day.

The idea is neat (you probably have to be the guy in the helmet to truly appreciate) but could use some mood modifications. It would have been cool to choose a landscape for the demo that fit the motif of the costume, suitably surreal. (via NOTCOT)
