Blue, Red, Yellow, Djungel (2002) by Simon Starling (b. 1967, Epsom) investigates the functionality of the artistic process. The work consists of an enormous, hand-printed curtain – a replica of a famous 1928 design by Josef Frank – and all the materials that were needed to make the curtain, from the tree cut down in Trinidad on 22 March 2002 to the tables on which the work was done and the pots of dye used in printing the pattern. It seems obvious that the time-consuming process of making the replica has no economic utility.
