Here's a link to BVHacker.

It's a free program to edit/create .bvh files.
As you will see, you edit a StickMan to create animations.
A good source of .bvh files can be found here:

along with alot of information.
One could also create .bvh animations and join a site to sell them.
(Incase anyone needs some extra cash or incentive.)
