File this video under "cool".  Royal Caribbean's Radiance of the Seas features a self-correcting billiards table that will adjust itself using a gyroscope when waves impact the cruise ship.

This cruise passenger posted a video of this pool table and it's really impressive how the balls don't move at all despite the ship swaying.  Pretty cool, eh?

Credit to Cnet for alerting us to the video.

Forgive us, it's almost time for vacation and one of our readers, Megan, sent us this odd, yet amusing video of a kid dancing all around his Royal Caribbean cruise ship.  We thought, "What the heck!" and share it with all of you.  Enjoy!
