Last night I was playing the Tron: Legacy soundtrack and my four year old son, Sam, (purely coincedental), started doing this crazy dance complete with disc throwing moves. It was so funny to me I posted it on YouTube.

Sam hasn't seen the movie but he has been fascinated with the toys and he saw the original movie. He has come up with some of his own stories about it. According to him CLU is named Sharkness because of the fins on the diecast light cycle.
