I would love to have a metal 3D print of a hyperdodecahedron, but I’ll probably order one in plastic first. The reason I want it: it is a symbol, which, like the Mandelbrot Set, has been given to us by technology, both in its physical form and its precise meaning. Until recently it has been intuited darkly — that is, in magical terms.

It would be incredibly cool if the plastic had properties that allowed the to be hyperverted to permit each of its 120 cells to be outermost.
