Highly suggest downloading Dia. It's so easy to use and makes
   cool stuff like this in a few minutes.* On a Philosophy group,
   the owner gave a difficult question about a guy creating a clone
   of himself, and asked "which one of them is more real?" Hard
   question.* So, I broke it down based on what he said, which was
   long and involved.* Anyway, in just a few minutes, I was able to
   whip this up.* Dia - look it up.* It's free, I've mentioned it
   before but I really like it and it makes cool stuff like this
   easy.[1]DPR
