ran across an interesting group via a friend on FB
...led to this http://kjmaclean.com/Geometry/Icosahedron.html
[author unknown...as to the following.]
"Geneticists have discovered that human DNA undergoes an evolutionary jump by activating some junk DNA when a person is sending positive frequencies through positive affirmations in gratitude. All linguistic languages can be mapped from sacred geometry in the Flower of Life form that visually shows that language is vibration. The Flower of Life is believed by many metaphysical traditions to be the 1st completed energetic life form God created and then complex sound waves of sacred geometric shape such as Archangel Metatron's icosahedron cube. Metatron's cube has shown up unbiased in many ancient traditions and religions. It consists of all sacred geometry such as the Flower of Life, Seed of Life, tree of life, the golden ratio, the golden spiral, the golden mean, Phi, Fibonacci, tetrahedron, hexahedron, octahedron and the dodecahedron. Archangel Metatron is believed by many ancient civilizations to be the right hand being of God/universal consciousness in the creation process.The message mapped out in the form of conclusive math as depicted in sacred geometry is a infinite unbreakable truth in nature, which is that everything exists in unity, harmony, and oneness. If any living thing doesn't realize this, then nature dismantles it and recreates new life forms that will work with the laws of nature...."
...it's based on Semi Semi Quintiles ...i.e. 18* if you think it over....
here's a top down view of an Icosahedron ...notice the 'Grand Semi Quintile' Matrix
