Mathematica provides polygon data of countries in the package
Miscellaneous`WorldData`. This is probably enough for fun, however you
will need some calculations to produce a projection onto a globe.
(Sorry, I have no access to these calculations right now.) I once
reduced the polygons of countries to polygons of continents, as the
number of countries turned out to be too great for a real-time
animation with the LiveGraphics3D applet. (See
http://theorie3.physik.uni-erlangen.de/~mkraus/globe.html for a
rotatable Mathematica graphic of a globe in the web.)

Hope that helps
