John Cake and Darren Neave (known as the Little Artists) question what it means to be an artist in a climate where art is a commodity. For just a few pounds, these works suggest, you can own your own Damien Hirst or Tracey Emin – indeed, you can build it yourself using a simple kit.

Yet these aren’t available in the museum gif shop – they’re one-off pieces in their own right, responding faithfully to the originals. Pretty meta.
