Here's an odd image that I found posted on a computer graphics forum, where it's the subject of debate about whether it's real or photoshopped. (They've even got a poll going about it.) I would vote that it's real, even though it's amazing that the kid could jump that high up on the wall. (Though with a running start, and being young and athletic enough, it's do-able.) If it's photoshopped, it's incredibly well done.
Update: It's been revealed as real. Apparently this guy (Ryan) has a talent for this kind of thing (jumping and seeming to stick to things).
