Zonohedrified Rhombicosidodecahedron with 870 Rhombic Faces
Manipulating known polyhedra in the effort to find new ones, as I did here, is made easy with Stella 4d, a program available at this website.

Fractiles’ Mandala, Based on Angles of Pi/7 Radians
Although this was based on something I constructed using the Fractiles7 magnetic tiling toy, I did not have enough magnetic pieces to finish this. The idea was, therefore, converted into a (nonEuclidean) construction using Geometer’s Sketchpad, and then refined using … Continue reading

A Rhombic Mandala Based on Pi Over Nine
The interior angles in these rhombi all measure π/9 radians, or some wholenumber multiple of that amount, up to 8π/9 radians.

Beginning the Fractiles7 Refrigerator Experiment
To begin this experiment, I first purchased two refrigeratorsized Fractiles7 sets (available at http://fractiles.com/), and then, early on a Sunday, quietly arranged these rhombusshaped magnets on the refrigerator in our apartment (population: 4, which includes two math teachers and two teenagers), … Continue reading
