xearth 1.1-10.1 (ia64 binary) in ubuntu feisty

Show a rotating earth on your X root window
 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 using either X resources or a command line
 option. Xearth can also render directly into PPM and GIF files
 instead of drawing in the root window; see the man page for
 details.
