Camouflage
Imperial War Museum, SE1
The story of camouflage begins in 1915, when the French army set up the "camoufleurs" unit: mainly artists, who deployed Cubist techniques to make themselves and their equipment less visible. Our own Army also used artists, including marine painter Norman Wilkinson, whose "Dazzle" designs aimed to confuse German U-boat commanders. It's all told in this supersize exhibition, which goes on to chart camouflage's journey from the battlefield to the catwalk, via art, music and film. (020 7416 5320). Until 18 November.
