The reason I'm thinking of making a NURBS driven DVD is that I don't really think there's many of them out there. I have one by the Gnomon Workshop titled "Modeling a GTP race car" which is great, but doesn't really go into huge detail. All the other DVD's I have are on rendering. Most of my techniques were discovered from trial and error, or from looking at other people's meshes to see how they tackled a problem. It just seems like 90% of the stuff out there focuses on polys. Sorry that wasn't much help, but hopefully my DVD might hit a niche that needs to be filled.
