2/11    If i have a smooth function of two variables, and want to turn it into
        a nicely rendered 3d picture, what is a good way to do that?
        mathematica would get the idea across, but i'd like something that makes
        a really nice picture with shading and lighting and such like the STM
        images on the IBM site.  any suggestions?
