That's for capturing the motion of the actor. What else do you have [over there]?

What I have right here is the new, the next generation of helmet cams from MoCap Design. If you remember, Daniel Craig was on a few episodes back and he had the older Version 1 helmet. This is the new Version 2 helmet. It's a much nicer design. It's got a 720p camera mounted on the front. We put a little 32 gig SD card on the side, battery pack, plug it in, everything's remote, everything's captured right up here in the back of the camera. This worked incredibly well out on stage.
