Glenn Stockton's name appears in Math Forum in connection with his gifting me a photocopy of the cited article @ Pauling House (Wanderers' Meeting), followed by a quick recap of its contents FYI:


Having finally seen Da Vinci Code for the first time last night (read book a long time ago) I was surprised at how little it did to exploit a rich set of geometric relationships. Fibonaccis were not tied to Phi very clearly, despite Pentacle.

Of course for a non-specialist audience, there's only so much you want to get into.

A mental schema I use:

Kingdom A:
Periodic Crystal Lattices:
Sphere packing schemes: SCP, BCC, CCP
Rhombic Dodecahedron, octet truss (A.G. Bell's "kites")

Kingdom B:
Aperiodic Lattices & Five-Fold Symmetry:
Icosahedron, Pentagonal Dodecahedron, Hexapents
Penrose tiles

In Fuller's scheme, these two neighboring Kingdoms are bridged by the so-called Jitterbug Transformation, which transformation I would expect to incorporate into some of our archived mathcasts (re: Math Casting see: http://mathforum.org/kb/thread.jspa?threadID=1425804&tstart=0 and of course my ToonTown proposal for PDX, a potential source for such vidclips).
