Product Description
This is the Hopf fibration preimage of the edges of a spherical tetrahedron, with holes so you can look inside. The slightly irregular hole pattern has been calculated by simulating a Gray-Scott reaction diffusion process on the surface.
Fatter rings have been added at the preimage of the tetrahedron's corners.
The whole thing has been stereographically projected onto 3D space and compressed radially using the atan function.
