Real-time Sunlight Earth Wallpaper for Ubuntu Linux

Watch the sun rise and set all over the world on this real-time, computer-generated illustration of the earth's patterns of sunlight and darkness on your Ubuntu desktop. The clouds are updated every 3 hours with current weather satellite imagery.

And every half hour, these images are composited and mapped onto a sphere by xplanet according to the relative position of the sun. The flat maps are post-processed by ImageMagick to cut off the 15 degrees nearest the north and south poles where cloud data is unavailable.

4 different types of maps: Mercator, Peters, Mollweide, Equirectangular
Dawn to dusk
Moon Phase
