The AuthaGraph

The problem of projecting the Earth’s spherical surface onto a flat page has vexed cartographers for centuries. Here’s one brilliant solution, the AuthaGraph, designed by Hajime Narukawa. This rectangular world map is made by equally dividing a spherical surface into 96 triangles, transferring it to a tetrahedron while maintaining areas proportions and unfolding it to be a rectangle. The world map can be tiled in any direction without visible seams.
