Waves of light in a 4X4 grid and electronically generated sound are varied as a function of the distance and motion of a viewer. I don't often think about electronics when I'm fishing, but often think of fishing when I'm doing electronics.
Sound is produced by circuitry that is sensitive to temperature and light as well as to the proximity of a viewer. It is not likely to produce recognizably repetitious patterns, and the volume level is considerably lower than normal conversation.
