In this digital performance experiment from the students of the Digital World and Image Group at Georgia Tech, an Arduino-based robotic duck spits out treats for kids when enough real ducks are gathered in the stream below. In order to get the real ducks to accumulate, the kids must feed them. The purpose of this experiment? To “digitally analyze and invert behaviors that are taken for granted in public spaces.” I can’t speak to that, but it looks like a lot of fun for the kids. [via Geekosystem]
