Ah, so you've been playing in the Mudbox huh? I've gotten my hands on it but haven't really had and projects come up that I would need it for yet. I think it is a preferable alternative to zBrush as it's interface is much more similar to working in a standard 3D application.
By the way, check out my most recent post. Do you think I should put it up as a print? I have it rendered to print at atleast 16x20 inches.
