I seem to remember reading (in one of Martin Gardner's myriad books on
mathematical recreations) about a sphere->sphere map projection that
mapped two Earth's surfaces onto one globe. He book mentioned the
quizzical look on peoples faces as they tried to figure out what was
odd about the globe in the inventors office. A spherical projection of
-that- globe would probably be perfect. I'll look for more data (Oh,
gee, a -reason- to reread M.G. books.)
