Metronome, a large digital number installation overlooking 14th Street.

Over a hundred feet high, it fills the outside wall of a building that faces Union Square. Plumes of white steam occasionally puff out of a hole ("The Infinity") at the center of a bulls-eye of 24 carat gold-covered bricks ("The Vortex"), topped by a giant hand ("The Relic"), none of which has
much to do with telling time -- except for the puffs, which are especially big at noon and midnight.
