 113 A 4D embedding of the real projective plane.
 114
 115 You can walk on the surface of the real projective plane or rotate it
 116 in 4D or walk on it while it rotates in 4D.  Inspired by Thomas
 117 Banchoff's book "Beyond the Third Dimension: Geometry, Computer
 118 Graphics, and Higher Dimensions", Scientific American Library, 1990.
