+.SH DESCRIPTION
+Animates a mesh geodesic sphere of increasing and decreasing complexity. A
+geodesic sphere is an icosohedron whose equilateral faces are sub-divided
+into non-equilateral triangles to more closely approximate a sphere.
+
+The animation shows the equilateral triangles subdivided into four
+coplanar equilateral triangles; and then inflated outward, causing the
+sub-triangles to no longer be equilateral, but to more closely
+approximate the surface of a sphere.
+.SH OPTIONS
+.TP 8
+.B \-visual \fIvisual\fP
+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.
+.TP 8
+.B \-window
+Draw on a newly-created window.  This is the default.
+.TP 8
+.B \-root
+Draw on the root window.
+.TP 8
+.B \-mode mesh | solid | stellated | stellated2 | wire
+Face/edge display style. Default mesh.
+.TP 8
+.B \-wander | \-no-wander
+Whether the object should wander around the screen.
+.TP 8
+.B \-spin | \-no-spin
+Whether the object should spin.
+.TP 8
+.B \-fps | \-no-fps
+Whether to show a frames-per-second display at the bottom of the screen.
+.TP 8
+.B \-delay \fInumber\fP
+Per-frame delay, in microseconds.  Default: 30000 (0.03 seconds).
+.TP 8
+.B \-speed \fInumber\fP
+Animation speed.  2.0 means twice as fast, 0.5 means half as fast.
+.TP 8
+.B \-count \fInumber\fP
+Depth (frequency) of the geodesic sphere.  Default: 4.
+.SH ENVIRONMENT

+.TP 8
+.B DISPLAY
+to get the default host and display number.
+.TP 8
+.B XENVIRONMENT
+to get the name of a resource file that overrides the global resources
+stored in the RESOURCE_MANAGER property.
