Not sure if this is the right section but, here goes. I don't have the illusion to show you but would like to know maybe where i could find it. let me try and describe it to you. It maybe by Escher but i'm not sure. If you could imagine standing on a hill top with a fishing rod in your hand and the hook and line is a pond. The pond appears to be miles away from you but the line is definately in the pond. The perspective deception is amazing as you know that the image can't possibly be right but it looks so real. ( boy this is hard to explain) I saw the image years ago in a book entitled - "TAKE A ANOTHER LOOK" Well that must be as clear as mud to you. STUNNED SILENCE!
