As shared with me by the wonderful @mgdm, using crystals for Dark Deeds just got even darker as it turns out one of the side-effects of doing nuclear explosive tests is you can end up creating Icosahedrite which is a quasi-crystal with fivefold symmetry such that x-ray crystallography imaging produces a pentagram.

A great find! Looking at the X-ray diffraction pattern I see alternating pentagons and hexagons - exactly like a type 2 geodesic as classified by R. Buckminster Fuller.
