Basically it's using velocity well. The dragging and throwing is pretty easy to figure out with basic physics (velocity and decay/friction). The rotation is a little trickier I imagine using some sort of Matrix transformations to dynamically decide a point to rotate around. Look for rotations around an arbitratrary point. I don't have enough knowledge to actually help you out directly but hopefully this will lead you in some direction.
Maybe there are some ready made classes...
