Welcome to the Burning Man - be prepared to participate and practise some radical self-expression. From a beginning of 20 people on a small beach in San Francisco in 1986, it has evolved into a one-week experimental festival attracting 48,000 people to the Nevada desertPhotograph: Piers Moore EdeThe first rule is: 'there are no rules'Photograph: Piers Moore EdeThe second rule is: 'nobody at Burning Man is a spectator' Photograph: Piers Moore EdeDress upPhotograph: Piers Moore EdeOr dress downPhotograph: Piers Moore EdeYou could even accessorise with a bike - and 'ride in expanse of nothingness' that is the Black Rock DesertPhotograph: Piers Moore EdeArt is an essential ingredient of the festival: 'Innovative sculpture, installations, performance, theme camps, art cars and costumes all flower'Photograph: Piers Moore EdeEach year is based around a different theme, last year was The Green Man Photograph: Piers Moore EdeThe theme for 2008 will be The American DreamPhotograph: Piers Moore EdeFestival goers are encouraged to participate through art - be it by wearing an elaborate costume or creating a piece of public artPhotograph: Piers Moore EdeInteractive displays add to the festival experiencePhotograph: Piers Moore EdeArtist Marc Ricketts of Portland, Oregon, poses under his art piece named Flight of Future Seed, 2006.

He is set ablaze on the Saturday night and follows a tradition started when Larry Harvey and his friend Jerry James burned a wooden man upon the beach in San Francisco on June 21, 1986, which brought a crowd of onlookers - the birth of a festivalPhotograph: Lyttle/zefa/CorbisThe crowd gathers around the fiery remains of the Burning Man at the close of the festival 2004Photograph: Scott Sady/Reno Gazette/APTwo muddy men, 2005Photograph: C Lyttle/zefa/CorbisThe people are the stars: a man with a painted face going by the name ‘Shaman Cat’ watches the sunset, 2003.
