Wow.

I don't know what to say.
 

Wierd Al and MC Escher kind of said it all didn't they.

P.S.
Extra Credit goes to the person who guesses the name of the equation written on the white board.
Or at least what field it is from.
 

I would like to point out that the reason Eric is able to offer said extra credit is that he watched the video, frame by frame, until he found a spot where those darn dancers weren't standing in front of the really interesting thing--the equation--and then pondered it all night until he was able to look it up on Wikipedia in the morning to verify that his guess as to what equation it is was correct. How can you not love a guy as white and nerdy as that? :)
