If you loved (still love!) M.C. Escher, or spent your childhood in the library looking at books of optical illusions, there are so many things on the Web for you! And me. Okay, I certainly have better things to do than sit around looking at Akiyoshi’s illusion pages, but sometimes I need a break. Looking at some of these is like looking at blooming spring flowers. And looking at others is like looking at blooming spring flowers after doing too many tours on the Tilt-A-Whirl at the carnival.
