Zonish Icosidodecahedron

Zonish Icosidodecahedron

To make this, I started with an icosidodecahedron, then added zonogons to the existing faces, in the ten zones along the three-fold symmetry axes.

A Twisted Version of the Snub Dodecahedron

Some might say the snub dodecahedron was twisted enough already, but I wanted to crank it up a notch, so I made this . . . using Stella 4d: Polyhedron Navigator, a program found at http://www.software3d.com/Stella.php.

A New Look at the Great Stellated Dodecahedron

In this virtual model, opposite planes have the same color. The beveling of the edges, this coloring method, plus the invisibility of certain parts, make the faces appear to be extensions of triangles, or triads of “v” shapes. Without this beveling effect on this coloring-method, however, it is easy to see that the true faces of this polyhedron are star pentagons. To see this second model enlarged — with this polyhedron’s traditional coloring — simply click on it.
