I started playing around with Sculptris, a free 3D modelling program (it's more working with clay than constructing). ADDICTING!
Unfortunately I have no experience with 3D (or animating) so far, but I really enjoyed it, and I hope to be able to learn and work some more with it in the future. ^^
So here's my first try on a Schnolf head.
The software is freeware, you can find it here:[link]
