 112 A 3D immersion of the real projective plane that smoothly deforms
 113 between the Roman surface and the Boy surface.
 114
 115 You can walk on the surface of the real projective plane or rotate it
 116 in 3D.  Furthermore, it is possible to smoothly deform the real
 117 projective plane between the Roman surface and the Boy surface while
 118 turning it or walking on it.  Inspired by François Apéry's book
 119 "Models of the Real Projective Plane", Vieweg, 1987.
