Summer Exhibition 2015, Royal Academy, London

For 247 years, the Royal Academy’s Summer Exhibition has offered a snapshot of contemporary art – and this year’s showcase is a riot of colour, variety and discovery with over 1,100 works spilling out from across its galleries. In the courtyard, visitors are confronted by a towering formation of steel ‘clouds’, created by Royal Academician Conrad Shawcross, before Jim Lambie’s kaleidoscopic stairs lead up to the Main Galleries. On view until 16 August.
