From Angela Gunn comes news of Flatland: the Movie. And also, unconnectedly, Flatland: the Film. So, two different animated versions of Edwin A. Abbott’s classic “Romance of Many Dimensions” available for your DVD player. The Movie has the bonus that Martin Sheen is voicing the protagonist, but the Film has the advantage that it’s already available.
Of course, as Angela points out, you could just read the original. It’s a favorite among physicists, especially those who work on extra dimensions. What they never seem to remember is how the book ends — protagonist A. Square, who has claimed to have proof that extra dimensions exist, is imprisoned for life on charges of heresy. Hmmm.
