Dirac Belt Trick

Time to put on your anaglyph (red/green) stereo glasses !

Feynman (or Phillipine) Plate Trick And this animation shows a belt version of the Feynman Plate Trick, using anaglyph wireframe.
Air On The Dirac Strings. This remarkable 1993 animation shows all three classic visualizations of the fact that the fundamental group of SO(3) is cyclic of order two, namely the Dirac Belt Trick, the Phillipine Wine Glass Trick, and Orientation Entanglement. It was designed by George Francis, Louis Kauffman, and Daniel Sandin, and the computer graphics were implemented by Chris Hartman and John Hart.
