Bands of coloured light shimmer in a curtain of mist. This apparition depends on the light projected from a precisely angled spotlight, as refracted and reflected by the water droplets, meeting the eye of the viewer. The resulting rainbow changes depending on the viewer’s position; no two viewers see the same rain-bow. Beauty was first shown in 1993 as part of a group exhibition in a garage in Copenhagen, an early articulation of Eliasson’s idea that the viewer is a necessary coproducer of the artwork.
