Not always what it seems
When I first saw this I thought it was a bug on a table with something spilled on it. Then I clicked to make it bigger and wow -- it's a beach.
Click on the photo to embiggen. It's worth it. And longer shot of the whole piece. One of the Sand Paintings by Andres Amador who does these all the time apparently. Only to have them washed away by the sea. Actually I've done similar sand paintings myself but on a much smaller scale.
Found on Facebook via my friend Richard Loomis who shares from Green Renaissance where they collect very beautiful images like this.
