Yay! A fun and unique tutorial inspired by yours truly but written and hosted by my friend. Be sure to check out his other tutorials. They are not Zbrush but they are handy.
There are also two free models you can download from his site. When I get the chance, I might make something from them and post them up.

PS: I’m having trouble with this stupid Zactivator.dll error for Zbrush 3 like some other guys on this board. But don’t worry, this tutorial is aimed at ZB2 (which is stable and it works…)
