One and Other
One & Other was a piece of performance art that took place in Trafalgar Square, London, during the summer of 2009. It was organised by Antony Gormley. 2,400 members of the public, chosen randomly by computer from over 30,000 applicants, each occupied the square's usually vacant 'fourth' plinth for an hour at a time.
Most participants treated the plinth as a stage. Some spoke on a mobile phone or blew bubbles, often with automatic bubble generators. Others took photographs, did drawings, or displayed placards for worthy causes. Some propelled paper planes; a few dared sit and do nothing.
