-It doesn't matter, however. You should just pick 'random'. It overrides all
-the other options, except for fps, delay and complexity.
+You have a tetrahedron with tesselated faces. The vertices on these
+faces have forces on them: one proportional to the distance from the
+surface of a sphere; and one proportional to the distance from the
+neighbors. They also have inertia. The resulting effect can range
+from a shape that does nothing, to a frenetic polygon storm.
+Somewhere in between there it usually manifests as a blob that jiggles
+in a kind of disturbing manner.
