Sunclock is a program that shows the current time of day with a 3d satelite map from the Goddard Space Flight Center. Night is in shadow. The day is bright.
During the night, city lights are turned on.
It can be set as your screensaver. It is my new screensaver.
You can also choose to see a display of the current sky over your current location. It will show you the visible constellations. This functionality could be easier to find than it is.tags:
