XEARTH, MOTIF_TOYS, Displays a shaded image of the Earth in the root window Xearth sets the X root window an image of the Earth, as seen from your favorite vantage point in space, correctly shaded for the current position of the Sun. By default, xearth forks a child process that runs in the background, updating the displayed image every five minutes to reflect changes in the Sun's position. Xearth can also render directly into PPM and GIF files instead of drawing in the root window. See the man page for details.
