Olafur used humidifiers to create a fine mist in the air via a mixture of sugar and water, as well as a semicircular disc (reflected by the ceiling mirror to appear circular) made up of hundreds of monochromatic lamps which radiated yellow light. The ceiling of the hall was covered with a huge mirror, in which visitors could see themselves as tiny black shadows against a mass of orange light symbolizing the sun. Many visitors responded to this exhibition by lying on their backs and waving their hands and legs. Art critic Brian O'Doherty described this as viewers "intoxicated with their own narcissism as they ponder themselves elevated into the sky. " Open for six months, the work reportedly attracted two million visitors, many of whom were repeat visitors. O'Doherty was positive about the piece when talking to Frieze magazine in 2003, saying that it was "the first time I've seen the enormously dismal space—like a coffin for a giant—socialized in an effective way.
