This kid's definitely awesome... if anyone's interested in some more really great skateboarding by someone in a nearly identical situation, check out Og De Souza from Brazil. He's been one of my top 10 favorite skaters for years- not simply because of his handicap, but because the guy just skates like a machine!
This is a profile on him:

As a skater, it's really neat to see that even with nearly identical physical situations, they not only rip but have distinctly different styles and approaches to their tricks.
Hell, a couple of tricks I do on ramp are partially due to a couple of things Og does (some early grab-handplant and varial tricks).
