These cool polyhedron light-fixtures were in Munich airport as I made my way to the gate, on Tuesday. Very nice, I thought – and I wondered if they have a mathematical name. It took a little bit of research, but it looks to me that the core is a rhombi-cuboctahedron (an Archimedean solid with 8 triangular and 18 square faces). And then when you add the pointy star extensions onto the faces, it becomes a great stellated rhombi-cuboctahedron. Yes! (Admittedly all the extensions are not the same length, but hey, close enough).
