If you are playing with 3D modeling, be aware of MakeHuman, a free open source tool for creating 3D characters. Written in Python, it integrates seamlessly into blender, and allows you to instantly generate a fully rigged and ready to animate human or near-human. It’s slider set has over a thousand morphs you can apply to modify your character, including (but not limited to) Age, gender, height, weight, body proportions, face shapes, eyes, nose, mouth, chin, ears, neck, hands, feet.. the list goes on. And it is licensed under the CC0 license from Creative Commons, giving you unparalleled freedom to use your creations however you like. The folks over at Games From Scratch did an excellent introduction video on this, which I am including here so you can see just how easy and powerful this package is.
