Here is a wide range of images that are some sort of illusion. Types of optical illusions, also referred to as visual illusions, include literal illusions, physiological illusions, and cognitive illusions.

Also mixed in the batch are photos that mess with your mind simply because of the camera angle when the image was taken.
