XGlobe: An enhanced version of xearth

“XGlobe displays the earth as seen from space on your X Desktop,
similar to xearth by Kirk Lauritz Johnson. The code to calculate
the sun’s position was taken from this program. The image of the
globe is updated at regular intervals. XGlobe uses a world map
image which is mapped to the globe. With a good map this can look
very nice (see Screenshots). It is possible to mark locations on
the globe. Unlike xearth, XGlobe works fine when using the KDE
Desktop Environment and switching between the virtual desktops. The
current version of XGLobe is 0.1. XGlobe is free software; it is
licensed under the GNU GPL.”
