Ripple
Interference between travelling circular waves
Circular waves from several travelling sources cross into a standing interference pattern, with bright ridges where the fronts meet and flares where they focus. The colour bends along the slope of the water, so it reads as a surface rather than as stacked stripes.
Rendering cost: medium. A few dozen samples per pixel: comfortable fullscreen on a discrete GPU, but cap the pixel ratio for a retina hero. How to tune it
