Yep, it is very similar to Zbrush (one of the big, industry-leading 3D sculpting tools) in that it feels like working with a solid hunk of material (clay), but Zbrush has a disconcerting number of options, bells whistles, doohickeys... This one just has a small number of tools that are pretty flexible. I downloaded it and whipped something up really quick--it is pretty much as easy as it looks, and intuitive (which is really important for someone as thick as me.)
