When you play a game on the computer, this is the basic graph of
   how it works. BUT, as I was looking at this, I realized that
   this is ALSO a basic model of human communication - so it is not
   just USER/COMPUTER interface, it is ALSO a graph of HUMAN/HUMAN
   interface.

   PS - you can also switch the ''Look and listen/User Input'' box
   with the ''Talk/Move/or not/Output'' box. It depends how you see
   yourself. Imagine yourself as a brain in a box going through
   this process and you'll see it then.

   I expect most won't see it or care much to try - but to those
   that can ''see'' what I see, let me know. -Ken :) (and please -
   correct me if I'm wrong. In this diagraph, your feedback would
   be the, well ''Feedback loop'' on the right. - My brain is
   waiting at the ''Your Senses are user-input'' part. It seems
   crazy but if you see it, I hope you go, ''Oh wow - yeah - that
   makes sense''. :) -Ken
