An optical illusion (also called a visual illusion) is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed in the brain to give a percept that does not tally with a physical measurement of the stimulus source.
There are three main types, literal optical illusions that create images that are different from the objects that make them, physiological ones that are the effects on the eyes and brain of excessive stimulation of a specific type (brightness, tilt, color, movement) and cognitive illusions where the eye and brain make unconscious inferences. They are also known as "mind games."
Not only are these cleverly drawn, they are beautiful in their own way.
Can you see all the skulls? There are more than one in the picture above.
The artists are so creative aren't they? I’m not sure which are my favorites because I like them all.
Poor Yorick he lost his head! Tee hee!
I really like the variety of these images. We are just looking at skulls but there are so many different kinds of them.
Even the skies get into the act with an astro skull. I think the skull in the picture below is made out of different kinds of containers.
Optical Illusions have always fascinated me. I have collected all kinds of them over the years. If you are interested I have been saving them on my Photobucket account. Take a gander if you want to, I am sharing them with the public and you can copy them if you wish the codes are up there.
