If you are interested in interaction and technology, I've updated my "Reflecting about Interaction" posts on my TSHWI (Technology-Supported Human-world Interaction) blog. I've embedded a couple of video clips that show how body movements interact with music applications. One is an interactive music wall, and the other is a staircase that senses people's movements and plays music and sounds as they move.
