Take a look at 'Sith' when Yoda rubs the top of his head - the movement is slow and deliberate. It isn't photo-realistic at all.
Look, I know the arguments for both sides, but when I was in Florida at MGM Studios and I reached across the barrier in the movie props warehouse and touched the gaming table from the Falcon, that was touching history and I would've cried if I wasn't all tough and manly (*cough*).
What am I going to do next? Will I reach across a barrier and touch Rob Coleman's old computer that has Yoda stored on it?
