Sharp Impact
I made this using Stella 4d, which you can find here.
New “NearMiss” Candidate?
As a proposed new “nearmiss” to the Johnson solids, I created this polyhedron using Stella 4d, which can be found for purchase, or trial download, here. To make it, I started with a tetrahedron, augmented each face with icosidodecahedra, created the … Continue reading

On Consistent and Inconsistent Combining of Chiralities, Using Polyhedral Augmentation
For any given chiral polyhedron, a way already exists to combine it with its own mirrorimage — by creating a compound. However, using augmentation, rather than compounding, opens up new possibilities. The most wellknown chiral polyhedron is the snub cube. … Continue reading

Compound of the Great and Small Stellated Dodecahedra
In this compound, as shown above, the small stellated dodecahedron is yellow, while the red polyhedron is the great stellated dodecahedron. Below, the same compound is colored differently; each face has its own color, unless faces are in parallel planes, … Continue reading

Two Different FortyPart Polyhedral Compounds
The polyhedron above is a compound of twenty cubes and twenty octahedra, colored by symmetrybased facetype. If the same compound is viewed in “rainbow color mode,” it looks like this: With this particular compound, though, there are two versions — … Continue reading
