If you suddenly meet 100 people in a fast food restaurant making some kind of "ballet dance" or you in a ToysRUs sees 200 people waving their hands at the displayed dinosaur you have probably seen a "Flash Mob". This new event is the newest "moving Cyberworld to the Real World" kind of thing. It starts off with people mailing their friends about where and when to gather and what to do there. It usually just takes on about 5-10 minutes and then it is over. The first Flash Mob was started by a guy "Bill" in New York, but it has now spread throughout the world - like when 200 people a few weeks ago marched to a London furniture store selling sofas and then they started to make mobile phone calls praising the sofas.
