Wow, that's exactly what I want to do! But I don't know what equation to
non-linearly you have put instead of the y on the "sine sphere". That's the
point for me. So it's this function:

sqrt( x*x + y*y + z*z ) - 0.9
            + sin( 12*atan2(x, z) )*0.051

(isn't it?) but on both y's that appear on the sqrt what should I replace for?
Thanks for all the attention. (I haven't seen the work you done seting the
product until today, i'm new on this web site. I'm so thankful, seriusly)
