Re: OT Re: Constructed maps

If you do your image as a straight cylindrical projection (vs Mercator
etc), the command-line software tool 'ppmglobe' will 'unproject' it
for you, generating an image that you can cut up into strips for
attachment to the surface of a physical sphere.   See
http://netpbm.sourceforge.net/doc/ppmglobe.html.

ppmglobe is part of the "netpbm" suite of command-line image
manipulation tools.  The way you use it would be something like this:

$ giftopnm mymapfile.gif | ppmglobe 24 | ppmtogif globestrips.gif

to generate an image that can be cut into 24 strips.
