So I somehow stumbled onto this software from Steam. I think it's main purpose is to give you a silly avatar while playing certain online games, but can obviously be used for video chat or just having fun. While there are other apps that do something similar, this one has the best tracking I've seen so far, and lots of fun avatars including a beer wench. While I don't like pewdiepie or his channel, he seems to have the best demo of the software:
