I have always been fascinated with optical illusions.  Check out these two websites for more illustrations like the two at the left.  Illusion-Optical. com and NIEHS KIDS' PAGES.
     Also, M. C. Escher, a master of optical illusions, was one of my favorite artists, and I used his work often way back when I taught geometry.
