A Two-Part Polyhedral Compound

The yellow component of this compound is a rhombic triacontahedron, while the red component is a slightly-stretched version of the strombic hexecontahedron (the dual of the rhombicosidodecahedron). The compound is derived from the truncated dodecahedron, and I made it using Stella 4d, which you can try for free right here.

Two Compounds Derived From the Snub Archimedeans

The dual of the snub cube is the pentagonal icositetrahedron. Both solids are chiral, so it is possible to make compounds out of each solid and its mirror-image. The polyhedron shown below is a compound of an enantiomorphic pair of pentagonal icositetrahedra.

The next solid shown was formed in the same way, except I started with the snub dodecahedron. This is the compound of an enantiomorphic pair of pentagonal hexecontahedra.

I did these polyhedron-transformations, as well as making these rotating .gifs, using Stella 4d: Polyhedron Navigator. You can try this program for free at http://www.software3d.com/Stella.php.

Two Compounds Derived From the Snub Cube

After stellating the snub cube many times (so many that I lost count), I ran into this two-part compound of irregular dodecahedra.

Like the snub cube this is derived from, this compound is chiral. Because of this, a four-part compound can be formed by combining this polyhedral compound with its mirror image.

I did all of this using a program called Stella 4d, which you can try for free at http://www.software3d.com/Stella.php.

This is the first stellation of the snub cube, one of the Archimedean solids. I made this image using Stella 4d, which you can try for free at http://www.software3d.com/Stella.php.

A 72-Faced Polyhedron Made of a Dozen Regular Pentagons and Sixty Kites

This polyhedron is the first stellation of the snub dodecahedron, which is one of the Archimedean solids. I made this with Stella 4d, which you can try for free at http://www.software3d.com/Stella.php.

These Are My People (Updated Version)

The folks at AncestryDNA just sent me this information. I was told, while growing up, that I was part Cherokee, on my father’s side, but that is apparently not the case. My mother’s map has nothing from Africa, so I can logically deduce that my recent African ancestors are on my father’s side. Of course, if you go back even further, we’re all Africans, since that is where human beings first evolved.
