Here are some ehnanced images of the eye.
The more I look at it the more I get from it.
1. It could be a black man. (No offense, but look for yourself at the images)
2. It could be a man committing suicide. I know that is sick, but the distortion at the bottom could be the result of the trauma caused by something like a gun shot. Look in the cats eye to right and you'll see something else, something like a barrel of a gun.
I really wonder what a cat sees. I would think being able to see dead people or things like this illusion depicts would be a curse far worse than any imaginable.
Then again, this could simply be a trick of the light, but hey, it sure is an interesting topic.
