this rigged doll is a very useful tool for demonstrations, stand ins, timing tests, ect. It's a great tool for anyone just starting to learn animation or sculpting, but it's also something I use to this day to set up scenes although I tend to use the superior version more often which you can find here...

Still this more simplified version can do everything that one can with the exception of the facial features. 

These are more cartoonish stylized figures in comparison to the superiors more realistic proportions. Though the rig does allow a lot of control over those proportions.
