The Planiverse (ISBN 0387989161) is a book by A. K. Dewdney, written in 1984. In the spirit of Edwin Abbott Abbott's Flatland, Dewdney and his students designed a vertical 2D world (ie E-W and up, no N-S) and considered the issues of biology and society for the inhabitants. Written as a travelogue, the protagonist Yendred crosses the world to reveal its features. The book has much more practical design and less social comment than Flatland.

The Planiverse: Computer Contact with a Two-Dimensional World (1984).
It?s a morality play as well as a treatise about how physics, biology, and society could work when one of our most common assumptions (a third dimension) is removed.
One could simulate the "Planiverse" in eToys but most of the functionality of the Morphs would not help.
"Planiverse" requires gravity while Abbot's "Flatland" resembles a world seen in a microscope slide.
