Three-Way Piece: Points
Three-Way Piece: Points is a sculpture on Revson Plaza, the bridge above Amsterdam Avenue. It was crafted in 1967 by Henry Moore, and gifted by the Miriam and Ira D. Wallach Foundation, which also funded the renovation of Wallach Hall.
The sculpture somewhat resembles a tooth (though this is up for constant debate), and it can be turned if enough people push. The Columbia University Marching Band has often taken advantage of this feature while chanting "We make holes in teeth!" as an homage to Cavity Creeps in the '80s vintage Crest toothpaste ads.
