 .SH 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.
