    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.
