Who would have thought that thousands of ball bearings rolling back and forth on a rocking coffee table could be so utterly fascinating? With Tommi Grönlund and Petteri Nisunen's Wave of Matter table in your living room, you won't need a TV.
The piece is like a horizontal version of those sand art picture frames, and as the table rocks back and forth every minute or so, the ball bearings flow from one side to the other. It looks and sounds a lot like waves crashing over sand on the beach, and since that's the hallmark sound effect of most white noise machines, it will probably put you to sleep in no time—if you could actually buy it.
