The world is not flat, it's a tetrahedron!
Various map projections try to approximate a sphere into a flat plane - Mercator etc, with varying amounts of distortion. But ultimately, the flat plane is a poor substitute for the real thing.
The AuthaGraph projection, invented by Hajime Narukawa in 1999 gets around this by essentially approximating a sphere to a regular tetrahedron and then unfolding it into a rectangular plane.
Other similar projections such as by Buckminster Fuller and B.J.S. Cahill have done this before but they do not produce a nice rectangular map, without holes or 'Here there be dragons' areas of imaginary sea.
My lovely wife bought me an AuthaGraph map for the wall from Geo-grafia a while back. The temptation was too great though, and I had to turn it into a tetrahedron, so now it has to hang from the ceiling.
