Petersen Graph with Ghost Symmetry

This represents a 3-dimensional drawing of Julius Petersen's most (in)famous graph.  This model is notable for a couple reasons.  First, due to a theorem of Neil Robertson, Paul Seymour, and Robin Thomas, this drawing must contain a pair of cycles which realize a Hopf link.  (Look for it!)  Second, this graph has pentagonal ghost symmetry.  Specifically, it has a 2-dimensional shadow which realizes one of its well-known 2-dimensional drawings, usually observed as a pentagram drawn inside a pentagon.
