DESCRIPTION

       Buckminster Fuller's  map  of  the  Earth  projected  onto  the  surface  of  an  unfolded
       icosahedron.  It  depicts  the Earth's continents as one island, or nearly contiguous land
       masses.

       This screen saver animates the progression of the dusk  terminator  across  the  flattened
       globe.  It  includes both satellite and flat-colored map imagery, and can load and convert
       other Equirectangular-projected maps.

OPTIONS

       --visual visual
               Specify which visual to use.  Legal values are the name of a visual class, or  the
               id number (decimal or hex) of a specific visual.

       --window
               Draw on a newly-created window.  This is the default.

       --root  Draw on the root window.

       --window-id number
               Draw on the specified window.

       --delay number
               Per-frame delay, in microseconds.  Default: 20000 (0.02 seconds).

       --speed ratio
               Speed of the animation. 0.5 means half as fast, 2 means twice as fast.

       --wander | --no-wander
               Whether the object should wander around the screen. Default yes.

       --roll | --no-roll
               Whether the object should roll randomly. Default yes.

       --stars | --no-stars
               Whether to display a star field. Default yes.

       --grid | --no-grid
               Whether to overlay a latitude/longitude grid over the map. Default yes.

       --flat  Display a flat-colored map of the Earth. This is the default.

       --satellite
               Display a day-time satellite map of the Earth.

       --image file
               An image to use for the day-time map.

       --image2 file
               An  image  to  use  for  the  night-time map.  The two images can be the same: the
               night-time one will be darkened.

       --frames number
               The number of frames in the day/night animation. Default 720.  Larger numbers  are
               smoother,  but use more memory.  The day/night animation happens if image2 is set,
               or if frames is greater than 1.

       --wireframe | --no-wireframe
               Render in wireframe instead of solid.

       --fps | --no-fps
               Whether to show a frames-per-second display at the bottom of the screen.

ENVIRONMENT

       DISPLAY to get the default host and display number.

       XENVIRONMENT
               to get the name of a resource file that overrides the global resources  stored  in
               the RESOURCE_MANAGER property.

       XSCREENSAVER_WINDOW
               The window ID to use with --root.
