Wow, you really caught up! Well done! Sounds like you learned a lot from trying it out! Fantastic progress.
I can see this becoming fun!
If you want to borrow another projector, I can help you organize one. I also have RFID tags if that makes things easier.
Also, if max/msp does the recognition not good enough, you could try processing.org, that also has a nice vision library.
If you want to show your progress today in class, let me know.
Cant wai't to play it!
