For our final 3D task of the term, we were asked to animate one of the rigs throwing a ball from one hand to the other, using the constraints mechanic we'd learned in a previous lecture. Below you can see my attempt: 

Personally, I found using constraints difficult, but after reading through the notes I'd made and practicing the exercise a few times I was able to create something I was happy with. I do think that the ball movement is a little slow, and the throw could be more dynamic, something to keep in mind for when I animate these kinds of actions in the future.
