Innovative audience research

This post from Chris Larry: "Thought you might find interesting the work we are doing at American History Workshop with our Telling Lives story capture technology. This technology allows audiences to answer question to a video camera that is than collected as a response database." I think that this is a very innovative approach to seeking audience feedback. Are there any others out there?

Chris: do you see this as a sustainable way to continue capturing feedback? How has the organisation used the information in their future development of programs?
