The Wish Machine, by multi-disciplinary practice Autoban, is a contemporary version of the 'wish tree' on which people tie notes of hope. Messages fed into the Wish Machine are carried through a tunnel of transparent pneumatic tubes and around the West Wing of Somerset House, before being deposited into the unknown, like coins tossed into the bottom of a well. The gesture of casting a wish into the dark reflects the profound hope of those among the biggest movement of people in recorded history, who search for utopian lands with dreams of a better future.
