The Mobius Band and Other Topological Surfaces

Movies:

      Gluing a Torus

       The Klein Bottle (also shows that Klein bottle contains a Mobius band)

      Visualizing real projective plane with VisuMap (pause at 11 seconds for gluing)
            Above video explained at part 1 and part 2

       The Mobius band and the projective plane
