In response to several people I made two images of the 20 vertex
polyhedron (whose dual was the yellow part of the original picture).
I think the rather large amount of perspective made it hard to
see there were 20 faces. Anyway, here are the two images.
The one with orthogonal perspective shows the symmetry better.
If I recall correctly there are 4 different edge lengths.
