Ask Slashdot: What To Do With Old Webcams?

An anonymous reader writes "I work as an IT administrator at a school. We have just upgraded our entire webcam inventory (about 45 webcams, model Logitech Quickcam Communicate STX) and have all the old ones sitting around. I would like to know what a neat project would be to make use of all the old ones. I was figuring there would be an open project somewhere that involved mass amounts of webcams."
