This reminds me of a old story... The residents in an apartment block kept complaining that the elevator was too slow. The building's owners got several quotes to upgrade the elevator but they were all too expensive and ran into many thousands of dollars. Eventually they were approached by a old man who lived on the ground floor. He said he could solve the problem for just a few hundred dollars. In desperation they agreed to give it a try and a few days later all the complaints stopped. His solution - simply install mirrors next to the elevators. It was enough of a distraction that people didn't mind the wait. I'm sure there are many more entertaining ways to distract than a simple ripple.
