After I found that old scene of mine, someone mentioned that it looked a
bit like a globe.  So I adjusted the tilt to match the Earth's, and placed
another sphere with an image map of the world (with all land in brown, and
Canada in red).  This seemed like the easiest way, since I do not have much
time, but if someone knows how I can make the land look "carved out," please
let me know.  What I want is for the land to be as thick as the supporting
longitude.  It may be somthing similiar to a height-field or an isosurface,
but I can't think of how to do it.  Any suggestions would be appreciated.

I created a similar globe for my IRTC 'Sea' Entry
(http://www.irtc.org/ftp/pub/stills/2000-08-31/asl.jpg). The land surface is
an isosurface created by wrapping an imagemap around a sphere and was
initially demonstrated by Gilles Tran
(http://www.oyonale.com/ressources/english/sources09.htm). You can get the
source from http://www.irtc.org/ftp/pub/stills/2000-08-31/asl.zip (without
the land imagemap). There is also a Pov-Ray 3.5 version of the code
(including landmap) in povray.binaries.scene-files (under thread 'Balls
collection take 2 (24k)', posted by Nico on 21/10/03).

Hope it is useful!

Cheers,
Ian
