If you haven't tried it, you should. Free, easy, incredibly intuitive 3D sculpting program. Did I mention free? Sculptris I was doing actual work today, but in between I sculpted this little derpywhale in about 30 minutes. It takes a little getting used to, but the learning curve was next to nothing. Try it! Post your results! I love playing around with new programs. I'll share more as I go.
