Visualizing the Fourth Dimension (Dimensions math dot org)

Science News - Seeing in four dimensions

Dimensions-math.org - a tool for visualizing four dimensions.

I guess it’s good to have an “American English” version (in addition to the British one)

 A walk through mathematics

A film for a wide audience

Nine chapters, two hours of maths, that take you gradually up to the fourth dimension. Mathematical vertigo guaranteed! Background information on every chapter: see “Details”.

Free download and you can watch the films online here or right down there.

The film can also be ordered as a DVD, a pity it’s PAL format only
