Check out this video of a security camera shooting a dining area as a cruise ship hits some rough seas.. it's amazing video.. you need to go into the video about a minute and a half before the big stuff happens.

Wow...
My dad is in the Navy and in their dinning rooms they've got these amazing mats that are basically anti-slip things that literally cling onto your plate like there is no tomorrow... food however does wander off but it saves on breakages.
(I have to admit that looks like awesome fun)
