"Flatland: A Romance of Many Dimensions" was originally an 1884 novella by the theologian and mathematician Edwin A. Abbott. It is 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. As of this writing there have been three films made based on this novel, of which "Flatland: The Film" is the latest.
"Flatland" was the first computer-animated feature film to be created by one person, without the legion of animators and technical crew required by larger-budgeted animation studios.
Two of the characters from the film, A Square and Colonel Triangle, were programmed as artificial intelligence "chatbots" that can be chatted with online at www.FlatlandTheFilm.com/chat.html
