Thank you for your many suggestions!  I tried the bigger cone as you
suggested and it worked perfectly.

	And other strange tags. ;) 

	I read some of the responses and I don't know if this will help but most
graphics programs, Photoshop, gimp have a "make seamless" option which
will correct the general problem with seams on a sphere. But not knowing
the image you are using I can't save if that will preserve the image you
are trying to use. Another thing is you must start with a mercator
projection image else the "poles" will be "scrunched" into points at the
poles. There is no good solution for that problem.

You are probably thinking of problems with mapping of
rectangular images onto spheres, while the problem with
his sphere was that it had tiny gaps (caused by roundoff
errors) between the CSG parts that forms his shape.
