    The circles will appear to move clockwise and counterclockwise depending on whether you are moving forward or away.

    Lightness illusions

    Go to this website for a small compendium of lightness optical illusions. The site also allows us to take the illusion apart and watch how its components work.

    Have a blast :D

    Shading Fades Away

    Stare at the center of the black dot for about 20 seconds. After a little while, you'll notice that the outside of the circle - the shaded area - starts to lose definition, and even becomes a solid color.

    The lines in the background distort the circle so that it appears squashed.

    Yes, very clever however you can resist the illusion by concentrating ver hard on what you KNOW is there.
