Things we're not hearing about during coverage of Olympic swimming: apparently the construction of the "Water Cube" (the Beijing National Aquatics Center) is based on the Weaire-Phelan sturucture. More specifically, the Weaire-Phelan structure is apparently the best known solution to the problem of partitioning space into cells of equal volume with minimal suface area. The edges of the cells in this structure make up the steel frame of the building; in order to make a more "organic"-looking pattern the pattern was sliced at an oblique angle.
Somehow I missed this in the New York Times on Tuesday. See also the Guardian from 2004 and Science News a few weeks ago.
