The spinning cube on the University of Michigan campus in Ann Arbor is listed as one of the "Uniquely Michigan UM-isms". The official title of the sculpture is The Cube "Endover." It was done by artist Tony Rosenthal using Cor-Ten steel painted black. It now stands in Regents' Plaza. It is said to be a gift of the Class of 1965 and the artist, who was a U-M alumnus (1936). Although seemingly massive and immovable, the cube actually rotates on its axis, given a gentle push. The cube measures 15 feet wide by 15 feet tall.
