I recently stumbled upon some wrinkled polyhedra. Such polyhedra have an unusually high amount of surface area, compared to their volumes, relative to most more-familiar polyhedra. The next one shown, below, is the dual of the first one. shown, above.

The two above were made before I received a request to slow down the spin-rate of the polyhedra I post, most of which, in the past, have had a rotational period of four seconds. This next one has the new, slower spin-rate (with T = 6 seconds) which I am now using:

I hope all of my readers prefer this change, especially since it takes 50% more memory, per file, to slow these down to 2/3 their previous rotational speed.

These were all made using Stella 4d, software which can be tried or bought here: http://www.software3d.com/Stella.php.
