The one bit of gear that Scott doesn't explain in this video is how his shirt works. Scott's wearing a state of the art optical camouflage cloaking shirt. These new shirts can be setup to either display random camouflage patterns (this is the mode Scott's shirt is in) or they can be connected to a video camera that you wear on your back that displays an image on the front of your shirt of what's in back of you, thus making the shirt invisible! This is exactly the same optical cloaking technology that the British use to cloak tanks.

Far-out Scott, keep up the good work!
