  I seem to recall learning about (after I had left, of course) of
something similar at the Alamo.
  I read that is puts one into the action in 1836.
  When I was in Langtry, TX there were holograms on the life and times of
Judge Roy Bean.  They were in individual viewing boxes.  Well, I guess three
or four people could crowd in to watch each scene.
