At Burning Man a few years ago they had a massive Rubik's cube installation. There were 3 control points spread around the cube, and the people at the control points had to collaborate to solve the puzzle.

Cute, but it has to be annoying to try to solve a Rubik's Cube without being able to flip it around. Also, not sure if it's due to the quality of the photos, but the colors seem a bit difficult to distinguish. But hey it's art, so who cares about any of that?
