I was fascinated by this fence in front of a fence. One fence is the dividing fence for a condo building and the other fence (the closer one in focus) is the fence dividing an adjacent parking lot. From memory, I think they were around 6-8 feet apart)What you are seeing is the second fence naturally blurred by the focus on the first (closer fence). This makes for a very complex image, don't you think? Amazing sometimes how simple things can become complex... you just have to see them! :-)
