   <_description>
-This animates a 4D embedding of the real projective plane.
+A 4D embedding of the real projective plane.
 
 You can walk on the surface of the real projective plane or rotate it
 in 4D or walk on it while it rotates in 4D.  Inspired by Thomas
 Banchoff's book "Beyond the Third Dimension: Geometry, Computer
 Graphics, and Higher Dimensions", Scientific American Library, 1990.
