Ripples in the sand

Ripples forms when wind flows across loose sand, forming some interesting patterns. The patterns that emerge are a result of the dynamics between the individual grains as they move across the surface. I bought a new camera last year and came across some of these interesting patterns on one of my first trips out with the camera. The sea in the background is the North Sea.
