This is obviously a bit of a simple shot, but I do enjoy taking these sorts of photos, and have a ton of them in my library.  The big, colorful HDR explosions are my favorites - and lots of fun - but I derive nearly equal enjoyment from these "little ones".  I was at Laguna Gloria Art Museum in Austin, and they have this nice little walkway and path down to the lake.  I saw this railing and just really liked the texture and colors, and the sort of gritty feel to it.
