This video truly has to be seen to be believed. These guys are doing something called freerunning, which wikepedia defines as "a form of urban acrobatics". Freerunning is apparently an emergent variation on another physical discipline called parkour (all of which is news to me). When I first saw this video I thought this stuff must have been cooked up somehow, but if you go to their websiteyou can see that these guys are definitely for real. Living proof that the creative impulse is alive and well.
