I found this website back in 2005. It is called Kung Fu Science. It is fun enough and silly enough to warrant a small advertisement in here.
"For a lighthearted exploration of the connection between physics and martial arts, punch up the new exhibit Kung Fu Science from the Institute of Physics in London." - Science NetWatch.
You get to follow the progress of a student trying to find the ability to chop a board in half with her hand using nothing but physics knowledge. What could be more fun than that? :)
