For any of you Carrara users who feel more comfortable sculpting clay rather than polygons, check out ZBrush at pixologic.com. I watched a demo of this groundbreaking program at Siggraph and was blown away at its power and speed. WETA Studios (the guys responsible for all the special effects on all the Lord of the Rings movies) have worked with Pixologic to create the new release due at the end of March. It's a 3D modeling/3D painting program that I think will change the way 3D artists will work dramatically. The attached image was modelled and textured in Zbrush and rendered in Carrara.
