Wing Chun Kung Fu Force Generation (AWESOME!)
There's a kicking demonstration, followed by Sifu Jim Fung's chum-kiu and one inch punch(!) and Sigung Chu Shong Tin's demonstration of Wing Chun stance by standing on one leg on top of a mahjong piece.
I personally found the 'Whoa!' at the end of the one inch punch video to be quite funny.
All in all some great demonstrations. I'll have to see if I can find more videos from this school.
