I wanted to combine the face tracker and the body tracker, so I added their code together into one file. That was relatively simple. I wish I could have used a more sophisticated body tracker which had more skeletal points and wasn't so jittery. Originally I wanted to make a 3D skeleton and skull which moved with the viewer, but I was unable to implement this. I added a 3D model of a penguin character I had made which moved with the tilting of the head to add an extra element and make the piece slightly more interesting.
