These were all derived in various ways from the polyhedra seen in the last two posts. The rest are smaller at first, but each can be enlarged with a single click of your mouse. Each of them has icosidodecahedral symmetry.
I used Stella 4d to make these images, and you can find that program at http://www.software3d.com/Stella.php.
Click on the smaller pictures, if you wish to enlarge them, one at a time.
Those last two were duals of each other. The next two are as well.
These next two are duals, as are the pair that follows them.
I’ll finish with one more dual pair.
All of these were made using Stella 4d: Polyhedron Navigator, which is available at http://www.software3d.com/Stella.php.
Medium: electrons and photons, arranged carefully using Stella 4d: Polyhedron Navigator, software I bought at http://www.software3d.com/Stella.php. There is a free trial download available at the same website.
Created using Stella 4d, software available at http://www.software3d.com/Stella.php.
After using Google to find the image of this galaxy, I used software called Stella 4d (available at http://www.software3d.com/Stella.php) to project it onto the twelve pentagonal faces of an icosidodecahedron, and then hid the triangular faces, as well as the vertices and edges — and then set the galaxies to rotate on the faces, as well as around the axis of the polyhedron.
I could not have made this without Stella 4d, software you can try for free (as a trial version), or buy, at http://www.software3d.com/Stella.php.
We’re all familiar with the radiation-hazard symbol:
And, of course, the biohazard symbol:
However, what if some unforeseen disaster threatens us with living, radioactive pathogens? Clearly, we need a radiobiohazard symbol for just such an eventuality, and I’m proposing the top picture here as a rough draft for one, inspired by the two already-existing warning symbols.
To the TSA, FEMA, the NSA, and the rest of the alphabet soup of “keep-us-safe” agencies: you’re welcome.
