I used MS-Paint and Geometer’s Sketchpad to make the designs on the faces, and then used Stella 4d (here) to put the whole thing together.

June 13 Special Election in the PCSSD
Voters in the Pulaski County Special School District in central Arkansas vote, June 13, on a millage extension. This isn’t a new tax, but just an extension of what we already pay in property taxes. The schools need this money to build classroom space, etc. for our growing student population. If you live in the PCSSD, please vote FOR this measure on June 13.
I used to donate occasionally to the ACLU, but then Donald Trump became president, so I set up a monthly payment plan.
If you’d like to join this part of the resistance, here’s a link to the ACLU, right here.
Augmenting the Octahedron with Octahedra, Repeatedly.
This is an octahedron.
If you augment each face of an octahedron with more octahedra, you end up with this.
One can then augment each triangular face of this with yet more octahedra.
Here’s the next iteration:
This could, of course, go on forever, but one more step in the series is all you will see here. I don’t want to get caught in an infinite loop.
Performing various manipulations of polyhedra is easy with Stella 4d: Polyhedron Navigator, which I used to make all five of these rotating images. If you’d like to try this program for yourself, just check out http://www.software3d.com/Stella.php.
