This weeks wallpaper is a single tree and its reflection on a small island, with a full moon rising behind it. The island and tree are dark, with the rest of the images in varying shades of blue. Icons do very well with this mostly blue wallpaper.
This is not a tornado in Namibia. Where is the flying sand? This is the shadow cast by the edge of a sand dune in Namibia. The picture was entered in the Italian National Geographic photo contest by Francesco Middei.
