This is a closeup of the eye on the Raywood Ash tree in my backyard. I just went out and measured it to give you an idea on how large it really is. Currently it is 14" wide by 4 3/4" high. What would be the iris is 6 3/4" wide by 2 1/2" high. It is less than 20 feet from my back doors to the tree and the eye looks directly into the house. Most visitors to the house are creeped out by it, but I think of it as a proctector.
