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