Pixologic makes ZBrush. I'm using v2.
I played through the demo and it was exactly like I had hoped it was so I am hooked. I've tried modeling softbody stuff in other programs but I sucked.
Other than my hands staying clean and I use a tablet, sculpting is sculpting, and I've always loved sculpting. I kinda feel like I can keep in practice without getting my office all mucked up. Though it is atm, with another sculpt of course.
Definitely dl the demo. If your keen on jumping in. Pretty cool!
