This 42-inch sculpture consists of 490
laser-cut steel triangles bolted together in an intricate pattern. The
outer form is tetrahedral and the inner texture is based on a
discretization of the gyroid surface. It was commissioned by the American
Mathematical
Society, and assembled with the help of hundreds of people at a sculpture barn raising on
the National Mall in Washington, DC. The photo shows it on display
at its permanent home at the Towson
University math department.
