Sometimes mistakes can be cool. I was stuck in rush hour traffic on the Pacific Coast Highway crossing the bridge over Agua Hedionda and snapped this image of the side of the bridge while waiting for the cars ahead of me to move again. I didn't check my settings which were left over from some night photography the evening before. Somehow I still think it came out interesting after some minor editing on the computer. Looking carefully you can see the 3 parallel wave patterns on each panel.
