this is actually very close to pseudocylindrical projections (an example is the orange peal like sliced maps, wiki says its called Goode homolosine). they look wierd, are dicontinous, but still largely preserve area and angles.

this one is very similar, except sizes are still wierd, and uses different radii spheres, which makes it both non angle and size preserving.
