Here is something very dear and special to me, perhaps the most special, a (re)discovery by Ken Lee Wheeler of the deepest secret of the Pythagoreans; you won't find this anywhere else unless you're some kind of initiate; this shows the divine proportionality of the 108 36 36 triangle and the 137.5 degree golden-angle and was taken from the book The Missing Secrets of Magnetism by K.L.Wheeler, free online.
