Imvery curious as to how humans can directly decode encrypted pictures. Do they stare at it for 10 minutes and go "ah, there it is". Paul E. Baclace peb@netcom.com

Well... maybe if it was one of those stereographic pictures, it would be a little bit easier. You just have to get your eyes in focus (and that's a bit hard for some people). Pling! You suddenly discover the hidden message, like "HITLER IS ALIVE AND LIVING IN ARGENTINA!" or some other related message. It's in 3-D, so the letters appear to be 5 mm tall! (Reminds me of when Jaws III was out at the cinema. :-)) Of course, you might have to print it out first. Sorry, just me being silly. ======================================================= | Peter Murphy. <pkm@maths.uq.oz.au>.
