Each of these polyhedral images (any of which may be enlarged with a click) was created using Stella 4d: Polyhedron Navigator, and this program may be tried for free at http://www.software3d.com/Stella.php.
Also, a question, for regular readers of my blog — you have probably noticed that this post has a different format, but it’s just an experimental thing I’m trying out.
Do you prefer this style of polyhedra-post, or the format I usually use?

Very creative, I like what you’ve done.

I’ll likely keep experimenting with this for a while, and see what other options WordPress, and this particular theme, offer.

Quite nice pictures.
The site looks attractive as it is, but I’m not sure if it’s improved or not. I suspect there might be an irresolvable conflict between wanting the images to be as large as possible and still wanting the sidebar with useful links to appear on the side where they’re available. One goal blocks out the other.
