LONDON , England ( CNN ) -- Thousands of dancers jammed a major London train station in a Facebook-driven `` flashmob '' mimicking an advertisement for a phone company . And the event last Friday evening was so successful that another is planned for next Friday in Trafalgar Square in central London . Plus , a group has been set up to organize another one at Liverpool Street Station a week later . Videos posted on the social-networking site showed Liverpool Street Station completely filled with people , counting down the seconds until the clock showed 7 p.m. , then dancing to music on their mp3 players as the hour struck . The sheer scale of the event came as a complete surprise to the organizer , a 22-year-old Facebook user who identified himself only as Crazzy Eve . `` I was watching TV and the T-Mobile advertisement came up and I thought , hm , let 's get my friends down to Liverpool Street and do a little dance , '' he told CNN by phone . He posted the event on Facebook and invited his friends , who invited their friends , he said , and so on until thousands of people had been told of the plan . `` At a quarter to seven people just flocked into the station like someone opened a plughole and the water went out , '' he said . `` They just kept coming in like sheep . As it grew and grew , I just thought , 'This is going to be huge . ' '' iReport.com : Were you there ? Send your photos and video . His main memory of the event is `` the volume of people -- you could n't see the floor , '' he said . He left after 15 minutes -- the scheduled ending time -- for fear of the police , he said , adding that he had deleted his name from the event Web site and refused to identify himself to CNN for the same reason . `` The entire main concourse was packed full of people dancing , cheering and screaming , '' said CNN 's Simon Hooper , who was passing through the station on his way home . `` There were camera flashes going off constantly . There were also loads of people crammed around the edge of the upper level of the station , looking down at the scene below . `` There were a lot of bemused commuters wandering around the edges , trying to get to their trains but nobody seemed to mind too much . Everyone seemed pretty good humored , '' he said . `` I think a lot of people who pass through Liverpool Street regularly are getting used to this sort of thing . '' British Transport Police also described it as `` mainly a good humored event , '' adding `` No arrests were made and no crimes were reported . '' Police did not have an immediate estimate of the crowd size , but more than 14,000 people joined the Facebook group `` Liverpool Street Station Silent Dance . '' `` It was both good cause we all stuck like a group did n't stop dancing inside and outside but bad cause of the people who could get anywhere but hey I love it WE MADE HISTORY RIGHT THERE ! ! '' one Facebook user said on the event 's Web site . `` Yeah I agree , there was n't any bad feelings there . Everybody just had a good time , apart from my friend being groped by some guy , but you 'll always get one , '' another wrote . The T-Mobile commercial which inspired the event shows several hundred people dancing in the station . The dancing in the advertisement appears to be spontaneous but was actually choreographed . It was filmed January 15 and has been widely broadcast since then . The success of the event has prompted Crazzy Eve to call for another silent dance at Trafalgar Square in central London on February 13 . A group has been set up to organize another one at Liverpool Street Station a week later . The station has a large open space with a balcony surrounding it . User videos shot from the balcony and posted on Facebook showed every available inch of space filled with people , many of them cheering , though the event was billed as `` silent . '' Flashmobs -- groups of people meeting and all doing the same thing together in public , from dancing to freezing in place -- have become increasingly regular events around the world . iReport.com : See an organized mass pillowfight in Taiwan . London 's Tate Modern art museum was the scene of a flashmob dance in 2007 , and hundreds of people froze in place in Trafalgar Square , then formed a conga line in 2008 . Charlie Todd , a comedian and founder of the New York group Improv Everywhere , which organizes flashmobs , says the point of the group 's `` missions '' is simple . `` We get satisfaction from coming up with an awesome idea and making it come to life , '' he writes on the group 's Web site . `` In the process we bring excitement to otherwise unexciting locales and give strangers a story they can tell for the rest of their lives . We 're out to prove that a prank does n't have to involve humiliation or embarrassment ; it can simply be about making someone laugh , smile , or stop to notice the world around them . ''
