So about 30 minutes before the banquet opened I was asked if I had something to project. I had been playing with the ESS library for processing and through something together in ~10 minutes.
Its simply two rows of white stripes which react to sound recorded through the microphone. But it looked fairly decent (sadly the pictures only show about two thirds of it) and people started interacting with it while waiting for their meal.
Thanks to Marty for the images :-)
