+SphereEversion draws an animation of a sphere being turned inside out. \
+A sphere can be turned inside out, without any tears, sharp creases or \
+discontinuities, if the surface of the sphere is allowed to intersect \
+itself. This program animates what is known as the Thurston Eversion. \
+Written by Nathaniel Thurston and Michael McGuffin. This program is \
+not included with the XScreenSaver package, but if you don't have it \
+already, you can find it at <http://www.dgp.utoronto.ca/~mjmcguff/eversion/>.
