Whatever this thing is, it is made of POV-Ray primitives that are 
patched with isosurfaces where they join.  The isosurfaces are blobbed 
with functions from the RoundEdge module of the Object Collection.

The white circle on the right edge of one the images is an unimplemented 
lamp fixture.  Pay it no mind.
