You are in a large glass  elevator.  You  feel the  elevator  going up and
down between the floors. The doors keep opening and closing letting people 
off at their floors.  You  look out  through  the glass and  see  visitors 
everywhere.  To get out at a level,  type  the number corresponding to the
level.
