Catfood Desktate combines satellite images to create a world map displaying day and night around the world - you can see sunrise, sunset and the changing seasons throughout the year. Desktate is a unique Windows enhancement that can continually update your desktop wallpaper or act as a screensaver. You can choose to rotate the map so that a specific time is always at the center of the screen or fix the map to a favorite location and watch the terminator between day and night move throughout the day. The new layers feature allows you to plot world borders, cities and other data on to the world map of your choice. Desktate includes three satellite images from the NASA Visible Earth project (two daytime and one nighttime) and allows you to select any image as the source. Links to suitable images are available on the Catfood Software web site.
