Hi Antonio,
There is a tidal stream that flows part way around the periphery of our local airport -- whilst walking around on a beautiful & calm day I noticed how striking the patterns were along the banks of the stream, with the sky reflected in the water ... and I wondered if it would look like jagged mountain peaks if turned around 90%. So I took the shot, and that's what I ended up with. I just wanted to see how many would "think outside the box" and realize that I've rotated it
