Thanks it was fun to make. 🙂
To get the human you want I think you will need to make it yourself.
If I were to do it I would film the action against a Chroma key background then bring it in to my editing software key out the background, export to images and import those images in to PI as a particle, this gives you exactly the action you need. The chances of you finding just the right action sequence for your needs I think are slim to none.
Also while there are extremely life like 3D models they are expensive and nothing works as well as the real thing.
