Come to think of it, a CD with sample line art and a buncha created tones would be a good potential product for PandaBuddha, hm? A tutorial would be a bit of a problem, at least for Photoshop because Adobe are pricks when it comes to allowing screenshots of their products in commercial projects, but clear explanations of the technique, screenshots of the results without including any Adobe chrome, and perhaps screenshots from OC and/or PSP would help? *ponders the possibilities*
