Check this one out . . . a clip of the TRON segment in the Video Games Live tour!
I found it interesting that every time an actor would have appeared on the screen on stage, video from the TRON 2.0 game was substituted instead. (Probably because the actors would have to be compensated for their appearances on-screen.) This makes for a nice advertisement for the game, I suppose. Provided anyone in the audience actually figures out where the scenes came from.
