Bay is the fellow who basically started/defined edge loops, and his current work is the very Gollum that you have probably seen from Lord of the Rings movies. I’m sure he’s done a lot more too.
He’s a genious, and a pretty nice fellow. I’m pretty sure Bay is one of the reasons why Zbrush 2 turned out the way it did. You can see a lot about who Bay is at his site:

And this is a test he did with the Beta of Z2 just a few months ago:

And I agree about the zscripts. I would have had quite a few made already but each and every time I make one, it never replays back correctly. I’m pretty sure it’s human error, meaning my fault, so I’m not blaming Pixologic for that. It’s just frustrating when I’m deliberately being careful not to do anything wonky with my modeling, and it still messes up.
