-A 3D immersion of of a Klein bottle that smoothly deforms between the
-Etruscan Venus surface, the Roman surface, the Boy surface, and the
-Ida surface.  Topologically, all surfaces are Klein bottles, even the
-Roman and Boy surfaces, which are doubly covered and therefore appear
-to be an immersed real projective plane.
-
-You can walk on the Klein bottle or rotate it in 3D.  Since all the
-surfaces except the Ida surfaces have points where the surface normal
-is not well defined for some points, walking is performed on the Ida
-surface.  Furthermore, it is possible to smoothly deform the surface
-between the Etruscan Venus surface, the Roman surface, the Boy
-surface, and the Ida surface surface while turning it.
-
-Inspired by George K. Francis's book "A Topological Picturebook",
-Springer, 1987, George K. Francis's paper "The Etruscan Venus" in
-P. Concus, R. Finn, and D. A. Hoffman: "Geometric Analysis and
-Computer Graphics", Springer, 1991, and a video entitled "The Etruscan
-Venus" by Donna J. Cox, George K. Francis, and Raymond L. Idaszak,
-presented at SIGGRAPH 1989.
