This one really starts to mess with your mind after awhile. In this
optical illusion picture, each box has a gradient that is going from
dark to light in one direction or the other. Although the vertical lines
are absolutely straight, each box will start to distort and look more
like a trapezoid pointing up or down, depending on which column you
look at. Don't stay on this page too long unless you want a headache!
