In this folder is a Mechanisto scene file called "Skeleton Sample". It is a demonstration of the upcoming skeletal animation features of Mechanisto. I had said that this would be a feature of Mechanisto 2.0, but it got to the point where all the other features were ready except this one, so I decided to hold off on this until the next release.
Basically, the skeletal animation feature will allow you to draw a stick figure and animate its motion. Then, you can apply a "skin" to the figure which can be made up of any number of other objects. The end result is that the skin moves like the skeleton underneath it, but you don't have to animate all the features of the skin.
All of the skeletal animation features are currently supported by the database and geometry engines, it's just that the user interface doesn't yet allow you to edit the skeletal motion. So for now you can open this file, look at it, and render it if you want, and even change the skin object, but you can't change the underlying motion. Look for this feature to be fully supported in the next release.
