A recent Tequila commercial had an interesting voronoi version of a model.
It had three rounded rectangles, with "voronoi webbing" between them.
An extensive google search found it to be Borromean ring based.
There are no free models of these types. The only explanation for how it can be created was "Blender and Meshlab."
Finally an explanation was found. The Surface Evolver program of Ken Brakke may be used to model it with "soap film" mathematics.

The page with mouse spin-able 3D images using WebGL 3D is excellent, and has about 15 variations.
The Surface Evolver *.fe files were not provided.
The data for the Seifert version was processed with Notepad++, and then imported to Moi with a new script based upon Michaels
ImportPointFile script, called ImportTriangleFile. The new script still has a few bugs to fix, due to being an amateur programmer.
The boundary curves appear to be ellipses.
A Surface Evolver *.fe file may be attempted.
Three orthogonal ellipses with a major axis to minor axis Golden ratio, using Moi's Golden snap script were created, but not used yet.
SubDiv9 may be applied.
The three boundary curve polylines could have a circle swept.
I'll have to learn how to do voronoi, as per Stefan, I guess with meshlab.
Ran out of room for .3dm, time to delete some files :-)
