heres a slightly different approach that is interesting but not nearly as well done as yours

heres the location of the image Link
the pattern is very strange.
here's something you might also find interesting (if you havent seen it before): instructions for creating a sotra semi-quasi 3D soccerball image using 3d studio max (im not sure if there are applications similar enough to studio max that you could adapt the process) Link
you might also luck out and find an usable image of a product made by one of my former employers called an earthball (like a 6' canvas ball on which we'd silkscreened the continents; wed include paints--several colors--so that it could be painted like a topo globe) based on a concept developed by the newgames foundation. id think someone must still make and sell them (the company i worked for has been bought, rendered, sold at least 6 times since i left) so it might be possible to actually create your own version--very large of course--photograph it and go from there
