Movie : Dimensions
This film can be watched online or downloaded here : Dimensions Home. It's mainly about some aspects of geometry and topology (dimensions 2, 3 and 4 but also complex numbers, Hopf fibration and stereographic projection) which are developed in 9 chapters. (details about each chapter are available here) This movie is supposed to be "A film for a wide audience " so, even if you're not familiar with topology, give it a try !
I wonder if Hipparchus really sounded like Salad Fingers?
