I can't really see much difference between it and free running, except that the "trickers" jump even when they don't have to.
Also, to call this a martial art is an overstatement, since it seems to be just a collection of moves from kung fu, free running and breakdancing. Can they really make use of that stuff in a combat situation?
edit. Okay, finished the video and I must admit that there were two guys (or the same one in two different shirts) that were totally awesome. But still.
