This is a really neat book I read years ago that is not only a funny book of victorian satire, but also a really short easy read primer on geometry of higher dimensions.
Flatland: A Romance of Many Dimensions is an 1884 novella by Edwin A. Abbott, still popular among mathematics and computer science students, and considered useful reading for people studying topics such as the concept of other dimensions. As a piece of literature, Flatland is respected for its satire on the social hierarchy of Victorian society. Isaac Asimov, in a foreword to one of the many publications of the novella, wrote that it is "The best introduction one can find into the manner of perceiving dimensions."
There are a couple of movie versions floating around, I caw a preview for a good looking one on you tube but haven't seen the movie as it is $29 and is not exactly blockbuster video kind of fare. Check out the movie site at http://www.flatlandthemovie.com/
