Canadian artists Marc Böhlen and J.T. Rinker have created UWM, the Universal Whistling Machine. The artists, interested in whistling as an ancient form of communication, built UWM as an experiment in linguistics. As someone whistles into the machine, it records and interprets the whistles, then whistles back. As we speak, the machine is building a database of whistles and logical responses in a pattern that Böhlen and Rinker say resembles language. And no, we're not sure what the dude in the red shirt is doing down below. That's another machine. One we don't cover. Yet.
