Yamakasi/Freerunning

i saw a documentary on SBS the other day. it's about these 4 guys who invented a new sport called Yamakasi or some people call Free Running/Parkour. these guys are simply amazing. if you think breakdancers are the most wicked thing, these guys blow breakers completely out of the water. their moves are so fluid you'd swear they could levitate. they eat breakers for breakfast (ok that last sentence sounded lame, but so what, these guys are so cool!) seems these guys train their guts out to get where they are; they're incredibly strong, and they can make moves that would snap a normal human being's legs in two. I went onto Youtube and found a couple of videos on this new 'sport' and found some vids on the 'original' 4 Yamakasi founders plus some guy called David Belle (and no, there are no special FX)
