Dimensions movie

Jos Leys emailed me to let me know about Dimensions, a computer-generated movie illustrating dimensions 2, 3, and 4. The trailer is here. The whole movie can be downloaded for free at dimensions-math.org. (It is also available on DVD.)

The movie was rendered using POV-Ray, and is joint work of Jos, Etienne Ghys, and Aurélien Alvarez.

Update. John Armstrong has downloaded and watched the whole movie, and has posted a lengthy review.
