When I was in college at App State in North Carolina, Kodak brought a
show to campus that I still remember today.
It consisted of hundreds of 35mm slides and 8mm or 16mm movie footage
shot by two guys that went on an adventure trip somewhere in the
western US.
The whole thing was automated with a recorded sound track and racks of
projectors.
It's a shame that shows like this aren't archived in ways they can be
periodically brought out and redone.
