Well, it's not the best for optical effects, but if you want the real thing, check out the sport of Parkour. It's the art of moving from A to B as quickly and efficiently as possible using only the potential of the human body. It's kind of a mix between rock climbing, skateboarding, gymnastics, martial arts, and urban climbing. Americanparkour.com is a good one, and search for parkour in the google video engine for some videos.
