Interesting Flash Mob Type Mp3 Experiment

By now, chances are that you've heard of the term "flash mob".  If you haven't however, it's a group of people who get together and perform a task spontaneously in what is normally a very public place.  Normally everyone in the flash mob knows what's going on.  In the case of Improv Everywhere's  latest mp3 experiment, the participants were given instructions as the night went on.
