Optical Illusions*
          
          Just so you know, all you kids out there who have trouble spelling words: 
          I keep accidentally typing: "illustion" instead of "illusion" - and having to go back and correct it.  
          So we ALL make mistakes! I just wanted you to know.

        Even I  can hardly believe this one, and I built this for you myself. (I didn't invent the illusion, though.) 
          The eye is completely fooled by what's around it - it's called "Contrast Contrast."
