Nice!

Just to prod you a bit: If you want to get rid of the hard mayavi 
dependence of femhub for 3D plots too, you could hack a 
(perspective/whatever) projection of 3D surface to 2D, remove invisible 
faces (normal points backwards) and plot the rest by the painter's 
algorithm (far faces first).
