Automatic Leveling Pool Table [VIDEO]

I went on a cruise for my honeymoon.  I don't remember ever once feeling like the boat was moving up and down much.  But I guess if you were going to play billiards on a cruise ship you would need one of these things.

Evidently, this self leveling pool table is on the Royal Caribbean cruise ship Radiance of The Seas.  It looks like an optical illusion!
