The Rain Room, an exhibition at the Barbican Centre in London, is a room from whose ceiling torrential rain falls. However, a series of 3D cameras are used to track where people in the room are, and it selectively stops the rain such that you effectively walk between the drops.
Random International invites you to experience what it's like to control the rain. Visitors can choose to simply watch the spectacle or find their way carefully through the rain, putting their trust in the work to the test.
More than the technical virtuosity necessary for its success, the piece relies on a sculptural rigour, with the entire Curve transformed by the monumental proportions of this carefully choreographed downpour and the sound of water.
