LOL ddaydreams, it was not my invention (wish I were so skilled). I am sincerely impressed by the creator of that image. And the others who know all about this stuff. (I'm just the messenger..) But it's fun:-)))) I've always loved optical illusions, but just now I'm well on my way to "hoptical delusions" (ie, beer overdose), so I'll bid you sweet goodnight.. Cheers, Diolma
