Mob are worldwide e-mail-driven experiments in organizing groups of people who suddenly materialize in public places, interact with others according to a loose script and then dissipate just as suddenly as they appeared.
You have to know someone to get invited. There's no website to go to for information, no ads in local papers -- the mob forms from e-mails that are forwarded from person to person.
The Mob Project is the brainchild of a man publicly known only as Bill, who says he works in the "culture industry."
