Water Magic by Jorgen Tharaldsen, who writes:

Here I stand at the narrowest point of a small lake, and as usual I have thrown objects into the water to see how it behaves visually. Because the lake was so narrow, only a few meters, the circles start to recoil from land. The effect is called, to my knowledge, interference, but I have yet to see anything similar, even after all these years of throwing rocks into the water. | via Nat’l Geo
