Most students have mobile phones. This project is to design and construct a system to allow these phones to be used to give instantaneous feedback in lectures, meetings etc etc For example they could drive a "worm" like the one channel 9 used to assess the leaders debate of the 2007 federal election.

You'll need to be smart and motivated. This could likely be turned into a commercial product. It would probably be best for a group of 2 or 3 students, but if you have an alternative proposal feel free to pitch it to me.
