Vibrating Pond

If you get a tray, fill it with water and then vibrate the tray, the surface of the water ripples in a really hypnotic way.

How about a large public water feature, like a fountain, but not a fountain, more like a gigantic vibrating pond?

The surface of the water would look so cool. And kids could jump in and feel the vibration on the bottoms of their feet. If you threw in coins, they would jiggle around everywhere.

What if instead of a vibrator, it was giant bass speakers installed under the fountain?
