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.
