Can an audience of 5,000 play a collective game of Pong?
"Each move of the paddle is the average of several thousand players' intentions. The sensation is unnerving. The paddle usually does what you intend, but not always. When it doesn't, you find yourself spending as much attention trying to anticipate the paddle as the incoming ball." Interesting book excerpt about the hive mind, and people doing as a group what nobody could do individually. I love this stuff. :)
