Here's a video of my progress so far: the cameras are filming a ball rolling down a hill (showcasing cutting), a ball in a pachinko machine (showcasing tracking in a complex environment), and a dialogue scene (showcasing different responses to different types of events). There is no sound, so find a friend: the two of you can improvise the dialogue yourself.
If you want to see more (or stay up to date), you can follow my senior design blog. Don't know anything (or care) about programming? No problem! The blog features lots of videos, jokes, and a few drawings of people being frightened by skeletons.
