The Earth screensaver will display an image of the Earth as currently illuminated by the Sun, from a variety of viewpoints.

You can view the Earth from the Sun (day side), the night side, from the Moon, or from an arbitrary altitude above any point on the globe specified by latitude and longitude. Day and night regions of the globe are shown based on the current date and time. The image of the Earth shifts location on the screen every 10 minutes to avoid burning in the phosphor in one location.
