The short animation Descendants is a wonderful and touching piece of work, but thanks to the CG Society publishing of the article it is even more than that; it is an excellent tutorial in animation production. When you read the Making Of, you get an understanding of what some of the challenges are in the animation process, and some of the options available for solving each one. So if you have ever considered making your own animation, watch this amazing example, read the Making Of, and consider how to apply its lessens to your own production.
