Some impressive skating. Check out video.google.com for some more footage.
How about doing 40mph standing on a 2 wheeled "board", powered only by the wind on a wing you are holding? Thats wingsurfing - Kitewing and Dirtsurfer, or a mountain board. - Excellent.
Take one Mountain Board, add Kitewing, 20mph winds, a large beach and ... throw it about.
