In Der Keplersche Körper und andere Bauspiele (1938), Gerhard Kowalewski showed a color-matching construction of a rhombic triacontahedron composed of 10 acute and 10 obtuse golden rhombohedra. Color-matching means that touching faces have the same color.


This Demonstration shows a color-matching dissection of a rhombic icosahedron and a Bilinski dodecahedron.

The Demonstration uses the same colors as Kowalewski except that we use magenta instead of white.

The construction is explained in [1, pp. 23–25].
