Don, how cool is that? Wow! I have used mine to tell if a surface was dark 
or llight, but nothing to compare to what you did.

In God We Trust,

Hi, all!

     When I read Peg's message, I remembered an experiment I once did with
my optacon.  I have kicking around here a couple of lenses from an
old telescope.  I took one of them and placed it in front of the
optacon's camera with the instrument set on white-on-black so that it
would register daylight as light on dark.      Pointing the lense and
camera around the room and with my finger on the array,I seemed to be
able to identify  a couple of chairs near me.  Maybe I did no such
thing but only imagined that the "images" i felt were the chairs I
already knew were there.  All the same, it was fun and I thought it
was interesting at the time.  I wondered what would happen if the
experiment were toughened up--made more rigorous--with real focussing
of the lense, etc.  Could Peg's friend get a travel aid out of that?
Far fetched?  You bet.  But that's what many people thought about the
optacon itself at its beginnings.

Yours sincerely,

Don Coleman--Mister Science, the telescope man!
