Turbulence

A Twisted Version of the Stella Octangula

For comparison, here’s the non-twisted, traditional Stella Octangula:

Compound of Four Non-Regular Triangular Dipyramids

The only irregularity to be found here is that the faces of the dipyramids are isosceles, not equilateral.

Compound of Three Non-Regular Square Diyramids

The only irregularity to be found here is that the faces of the dipyramids are isosceles, not equilateral.
