Zero to Infinity + the Tanks

Rasheed Araeen's dynamic work Zero To Infinity at the Tanks, the newest exhibition space of Tate Modern, consists of 100 uniform lattice cubes initially arranged in a 10 by 10 array.  Guests were invited to move the cubes around to form a spontaneous configuration out of infinitely many possibilities.  The artwork challenges the idea that a work of art has to be a fixed object conceived by a single individual.
