Not Maya but interesting enough for a post me thinks:

Been studying use of knots in early Celtic/Druidic culture too . . . most interesting. Seems they have far more significance than we have yet to discover . . . in addition been reading some papers on Protein Similarity from Knot Theory . . . .and : Knot theory as the math helper for the internal structure of physics particles such as photons, electrons and to tell the geometry of the overall Cosmos . . .

What a wonderful life I lead :-)

Namaste,

David
PS. I Love Knots :-)
