Yeah, Mathematica is probably not used much on DeviantArt. It's more of a hardcore application used by scientists and engineers, but it can plot functions in 3D and export meshes, so I can use it for art. I use Geomagic to smooth meshes, fill holes, and such. And of course, Maxwell Render... That was the whole reason I got involved in this because I can now take perfect photos of impossible objects made from impossible materials. Thanks!
