Rainmaker (until 3 March 2012)

If the weather outside isn’t damp enough for you this winter, you can always top it up at the Barbican.

The arts centre has turned its Curve space into the ‘Rain Room’, a carefully choreographed downpour of some 2,500 litres of water. The exhibit, which runs until 3 March 2013, uses 3D depth cameras to pinpoint your position and ensure that wherever you walk, you won’t get wet. Designed by experimental art group Random International, Rain Room has proven a hit so far, so make sure you get there early in the day.
