An adventure in solid geometry wherein our spherical planet is reformed into a cube, engendering many odd effects -- rain falls at an angle, the oceans gravitate to the centers of the sides, and unexpected pyramidical forces send Cubeworld on a hairraising journey through the solar system. If you liked Flatland, you'll like Cubeworld.
