To the AUDITORY list -- I recently gave a talk at Penn State's TEDx conference on sonification. I had 12:00 to define, justify, and demonstrate some work I've been doing with astronomical phenomena with some very interesting people. I managed to do it in 13:46. If anyone is interested in seeing/hearing it, it's online here: http://www.youtube.com/watch?v=aQJfQXGbWQ4 Mark Ballora
