Quote - Bill, I thought I read a post of yours somewhere where you said your goal was trying to get things as photorealistic as possible.  I guess I'm mistaken.  

No, you're not mistaken. That is my primary goal with the study of shaders.

The reason that it is not a goal for me to figure out NPR shaders isn't because I have no interest. It's because I already know exactly how to do them. A learning goal has to be something you don't already know. Knowing how to do them already, it's not a goal for me. That hasn't got anything to do with whether or not I'm interested in it. I was, until it wasn't a puzzle anymore. Now I'm not interested because it isn't a puzzle. 

Similarly, at one time it was my goal to get a driver's license. That is no longer a goal. My interest in driving has not waned - but it's not a goal.
 
But if people asked me how, I'd be happy to show them any style at all.
