well... I didn't expect an exact reproduction :p a 3d scene wouldn't be so impressionistic for one. I just meant try to mimic the color qualities, maybe simulate brush strokes. I got sort of the effect I wanted once by toying with the various cel shaders that were floating around but the look required very precise lighting that wasn't always best with the cel shaded characters. The reason I need such a shader versus just doing the background up with photoshop filters is so that the characters can more easily interact with the background
