A technically equivalent but more dramatic version of this
that I used to use back then was a shell script that would
prompt for the name of a file to display, and then display the
file whose name the user entered.
This would make steam come out of the ears of the IBM mainframe
people because it wasn't possible to do that on the IBM mainframe
in use at the time.
