TV Man or Five Piece Cube with Strange Hole is a 1993 mountain rose colored granite and steel sculpture by David Bakalar, installed on the Massachusetts Institute of Technology (MIT) campus, in Cambridge, Massachusetts, United States. The five abstract, organic elements of the sculpture reflect the influences of Constructivism and Surrealism on the artist's style. The geometric forms use negative space to help compose an anthropomorphic ensemble.
