OT: Currents, North, etc.

I'm curious:  has anyone ever tried to make a globe of a con-planet?  I'd
like to try and have several ideas, but thought I'd ask before re-inventing
the wheel......
For a first effort, I'm thinking of buying a largish beach ball and painting
on it, but I can see how getting the lat. and long.lines straight and
accurate might be a problem; or creating paper gores and pasting them on
(the professional way I think). etc. etc.
Is it possible to buy a blank globe, with lat. and long. already imprinted?
Any suggestions?
