"I call our world Flatland, not because we call it so, but to make its nature clearer to you, my happy readers, who are privileged to live in Space. Imagine a vast sheet of paper on which straight Lines, Triangles, Squares, Pentagons, Hexagons, and other figures, instead of remaining fixed in their places, move freely about, on or in the surface, but without the power of rising above or sinking below it, very much like shadows, only hard and with luminous edges, and you will then have a pretty correct notion of my country and countrymen. Alas, a few years ago, I should have said 'my universe': but now my mind has been opened to higher views of things."
This unusual toy, called Flatland Plane, consists of a Halbach array of 100 neodymium magnets, and a number of pieces of pyrolytic graphite that will float just above the surface of the magnets. Inspired by the 1884 book 'Flatland', written by Edwin Abbott (from which the above quote is taken), the story tells of a 2 dimensional world where figures of various shapes could move around in just that one plane!
The toy has been hand made by Anthony Rizzo, of Fort Thomas, KY. The magnets sit in a box made of cherry wood, and he has made a separate, smaller box to hold the pieces of pyrolytic graphite. We only have a few of these wonderful 'Flatland Planes.'
