The Color-Matched Dissection of the Rhombic Enneacontahedron
This is The Color-Matched Dissection of the Rhombic Enneacontahedron.
The plexiglass shell, shown empty below, opens up and is filled with 120
rhombohedral pieces in five different shapes. The pieces are constructed
of acid-free card stock, assembled with tape, colored with five colors,
so that opposite faces are always the same color. They fit together
to fill the solid, matching color to color, resulting in a symmetric coloring
of the 90 visible outside surfaces. This was the topic of my talk at the
1997 Art and Math Conference, in Albany.
