The column on do-it-yourself tensegrity generated a couple of interesting responses.  First, “bonooboong” shared a design for a building that uses tensegrity as a sculptural element:


And second, Robert Coolman refined the classic six-strut tensegrity structure, using elastic hair bands for the tension elements to provide uniformity and color, and groups of four narrow dowels (skewers?) for the struts:


Note the clever arrangement of colors which results in all four colors meeting at every vertex, and in all four colors comprising every non-planar quadrilateral.  Also, each possible set of three colors occurs on exactly two opposite faces of the icosahedron. is still accepting other mathematically meaningful tensegrity topics…
