       The original Dymaxion Map image is copyright © 1982 by The Buckminster Fuller  Institute.  (This  program
       does not use their imagery, only similar trigonometry.)

       The Dymaxion Map was covered by now-expired US Patent 2,393,676 (Richard Buckminster Fuller, 1946).

       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.

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.

--visualvisual
               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-idnumber
               Draw on the specified window.

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

       --speedratio
               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.

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

       --image2file
               An image to use for the night-time map.  The two images can be the same: the night-time one  will
               be darkened.

       --framesnumber
               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.
