How about it Pixolator?.
There is so much great Zbrush art about be great to have a book dedicated to it.
What from like Ballistic Publishing or something? That would be cool but it would be mainly filled with stuff from about 10 guy’s. (I shouldn’t say that), But there literally are about 5, or 10 guys that the quality of their work is so out of this world in ZBrush comparatively it’s hard to look at anything side by side with theirs in the same light. That’s just my opinion, and I am finding new galleries with really good stuff every day as I search ZBC for a better understanding of the application.
Give it a little time though. I’m sure it will happen fairly soon after a few more people get used to the application. You’ve seen the results. They are astounding.
A lot of us liked the applications potential (especially me) but before Z2 the interface was keeping some people (at least me) away from it.
Now I’m scouring ZBC for scripts to find the answers to the questions that I need to be answered to produce quality images. Plus the Mac version of Z2 isn’t ready yet, and I’m playing catchup in ZB1.55b. It’s a slow but necessary task if I want to jump right into Z2.
But you can’t deny the results you see coming from this multifaceted, multi-use application. It’s the 3D tool of the new decade if you ask me. It does a lot. It can stand alone, but it also plays well with others. Like I said. I think it’s the 3D tool of the new decade. 
I have to agree. I’ve been raving about this thing and showing all my friends @ school this site. Its amazing!
