Actually you are probably seeing it right. What you are looking at is water running over the outflow of an aquarium filter. The ripples are actually the shadows created by the ripples as they pass over the plastic plate.
Or black volcanic beach sand with little ripple waves. (sorry, my head is somewere else besides winter in the northeast ) I used to love the water sounds of my aquariums (at one time I had ten set up at once)
