Made with Sculptris
(a work in progress)
Start with a sphere, use your mouse to push, pull, model - like working with clay - also paint and texture on your model which is a very complicated process in many 3d programs
For a free program, this is awesome does some of the stuff the big expensive ones do - FUN - and way simpler to use than those others.

I'm kinda new at this program so learning as I "sculpt"...
