There's a few map projections I really like that don't have most of these problems: HELAPIx[0] and Dymaxion map[1]. HELAPIx is designed to have pixels of the same area, and Dymaxion is designed to have the least distortion. [0]: http://healpix.jpl.nasa.gov/ [1]: https://en.wikipedia.org/wiki/Dymaxion_map

Probably my favorite are the Myriahedral projections[1], basically the Dymaxion map, but with ridiculous number of faces. In his paper he also unfolds a fractal[2].

Is there some nice explanation of how the projections between various EPSG codes work? I converted one projection into another but in QGIS or in python pyproj, but except for the very basics I have no idea what is going on.

I don't yet have a very good understanding of the whole EPSG code system yet either. :s
