Natural abstract

Another dull but warmer day.  We both headed out for a short walk taking the route I took yesterday.  I noticed that I had lost yet again the cover for the cameras flash.  I checked it before I went out yesterday and noticed it had gone while I was out.  Looking on the internet it seems this is a common problem and it likely fell off when I took the camera out of my small rucksack so we headed to this point first.  Not surprisingly I didn't spot the small cover.  I had in mind that todays abstract Thursday topic was natural patterns and took this shot of the beach.  It seems the topic was symmetry but maybe you can argue there is a top to bottom symmetry.
