Ideas for Final Project

I have decided that I'm going to use a webcam for my final MAX MSP project.

The idea currently is that I will record a basic blues backing track on my keyboard at home, and using a combination of MAX and a webcam, play an improvised blues solo over it simply by waving my hands and moving.  Audience interaction will be possible.

There are other things I'd like to be able to do, but this is the basic idea for now.  I've signed up to the Cycling 74 forums and am seeking help from users there.  I plan to build my own patch, using elements and ideas from other patches I find online.

There are a lot of patches and things from other users I can take or use in my own patch; for example, I would like to use something similar to what this man has done.  In the video, he uses the motion picked up by the webcam to adjust the sound, at first using it like a theremin, and eventually, using it to control an entire array of sequences and sounds.

Another example of something I'd like to use can be found here.  In the video, the artist has set the webcam up so that his hands control different things; his left controls the pitch, and his right hand controls the volume.  He also uses a handheld android device to fine tune the notes.  Using a webcam, he is controlling three variables.  He shows how he's done this by splitting up the webcam's feed into three different sections.  If I can work something like that into my own patch, it will mean more freedom in my final project and performance.
