Xearth

Set the root window to the image of earth

by FreeBSD on November 21, 2012

Xearth sets the X root window to 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 updates the displayed image every five minutes. The
time between updates can be changed with the -wait option.
Xearth can also render directly into PPM and GIF files
instead of drawing in the root window.
