Now ive updated my site with a screenshot. It seems you just have to tinker with the settings (which are all labled) to get the right effect your after. The screenshot is just of some terrain and i adjusted the color values of the shader along with the cutoff values. The only problem is getting your lightpos set properly. I think it would be cool if you could set it in a way that it could dynamically detect the closest light and use its pos instead. This however, is just a pipedream i think.

@Drew: told ya I'd get you your NPR shader.

I am also going to try the mettalic NPR aswell. Now we just need stencil buffers . Anyways enjoy.
