I have really wanted to do this but I don't where I would get funding.
It would be public art... an experiment in psychology... an experiment
in human behavior.  I would like to have a wall in various places
around the globe that is in contact with others periodically changing
1-1 mappings.  What if historically antagonistic people could talk
through a wall that prevents physical contact or fear of place or
situation?  Would the wall become a forum for discourse or hatred
display or what?  Would friendships arise between people who can't
touch or move from location?  Would relatives meet across barriers of
politics, and space?  Could people better work out their own problems
over distance with strangers than traditional means?  What would be
the effect on third party observers that are allowed to watch but not
participate?  Would people give others the gift of performace such as
play music or tell stories because you can't give anything physical
across the barrier.  What if three way conversations could be set up,
what is the best way to make that work?  etc.  If I could think of who
is crazy enough to fund such an off-the-wall experiment I would write
the grant.  But this seems too wild for any normal funding agency.

This sounds workable with a lot of room modifications.  Could be interesting.
