Op Art on a Dodecahedron
I used Geometer’s Sketchpad and MSPaint to make the designs on the faces, and then assembled the dodecahedron with Stella 4d, a program you may try here.

A Dozen Pulsating Dodecahedra
To make this using Stella 4d (available here) I started with an icosahedron, placed a dodecahedron on each of its vertices, then rendered the central icosahedron invisible. The slight pulsating effect is caused by the program fitting the polyhedra tightly … Continue reading

The Dodecahedron, Made from Smaller Polyhedra
The polyhedra at the vertices are rhombic triacontahedra, and the yellow edges are elongated rhombic prisms. This was made using Stella 4d, software you may try for free at this website.

Four Sets of Five Circles On Each of the Faces of a Dodecahedron
After using Geometer’s Sketchpad and MSPaint to make the image on the faces (seen alone in the last post), I then used Stella 4d: Polyhedron Navigator to project these images onto a red dodecahedron, and create this .gif. Stella is … Continue reading

A Hybrid of the Tetrahedron and the Great Dodecahedron
I made this by stellating a dodecahedron repeatedly, but doing so with Stella 4d, the polyhedralmanipulation software I use (available here), set to use tetrahedral symmetry, rather than the higherorder icosahedral symmetry (which I often call “icosidodecahedral” symmetry) inherent to … Continue reading

On Convex, Dodecahedral “Fair Dice”
One of my early introductions to polyhedra came through playing the game Advanced Dungeons and Dragons (AD&D), which uses a standard sevendie set which includes the five Platonic Solids, plus two “d10s” (either tenfaced dipyramids or trapezohedra) which are used as … Continue reading
