As announced a few weeks ago in this column, I made a large mathematical artwork at a public “sculpture barn-raising” on the National Mall in Washington DC last weekend.  Hundreds of people helped me screw together these 490 laser-cut triangles into this structure which illustrates a discretization of the gyroid surface.

Photos and a detailed description of its making are online here.
