All-seeing eye prototype symbols for my PC case-modding "Egypt Project".
"In its current form, the symbol first appeared in the west during the 17th & 18th centuries, but representations of an all-seeing eye can be traced back to Egyptian mythology and the Eye of Horus. However, it is first in Buddhism that the eye is associated with a triplicity. Buddha is also regularly referred to as the "Eye of the World" throughout Buddhist scriptures (e.g. Mahaparinibbana Sutta) and is represented as a trinity in the shape of a triangle known as the Tiratna or Triple Gem. 17th-century depictions of the Eye of Providence sometimes show it surrounded by clouds. The later addition of an enclosing triangle is usually seen as a more explicit trinitarian reference to the God of Christianity."
