I recently came across the gravity-defying antics of one James Kingston. He's part of a Parjour Agency called Ampisound, where several guys appear to make a living out of climbing ordinary things. Here's one where he leaps around the rooftops of Cambridge (England). I found my head swaying with the movement!
Then it led me to another one where he climbed a crane. With no gear! He proceeded to walk out to the end and hang off it by one hand.
Dude has no fear. Needless to say, don't try that at home!
