You have entered a very strange room indeed.  As you stare off in other
directions a strange affect hits your eyes.  The walls appear to be moving
and shifting in regular intervals.  You attempt to time your next move so
that a wall doesn't suddenly appear where you are.  You also notice that
looking in certain directions gives you the impression that this is a
never-ending maze of rooms.  Looks like you are in for a long day.
