Produced by Mixografia, and permanently installed on the facade of the Remba Gallery, Borofsky's "Turtle Clock" is a working timepiece measuring 15 feet by 40 feet by 1 feet. The sculpture consists of 72 interlocking copper turtles - 12 rows of 6 turtles each with the first row on the left being 1 o'clock, the next row 2 o'clock, and so on. The rows of turtles mark the hours by moving their heads in and out of their shells (motorized by a digitally controlled compressed air system).
