@Brian: I didn´t save the file because it was very basic. The idea was to show like with a poweful tool like MoI you can make pretty things with a few steps (obviously, the final model may be more refined). But I have made it again and I have seen that is not necesary to divide the profiles in two "hemispheres" (less steps) :-)
You get a very nice renders, I´ll be grateful for your render.
@steve: anything like that? :-P
