At this time of year I like to show some of the Dimensions series. Beautifully designed and distributed under a Creative Commons License, the series is free to download and show in class, and gives an excellent overview of projective geometry in two, three, and four dimensions! Incidentally, the animations were created using POV-Ray, a free ray-tracing program that generates photo-realistic images using precise mathematical modeling.


  1. Thanks for sharing. I really enjoyed it.

  2. interesting material, where such topics do you find? I will often go

  3. [...] How would you like to experience mathematical vertigo? Check out the film series Dimensions. [...]
