The 2nd Sceneofest Sound Exhibit was installed in the center exhibit hall and had two stations:  one near the internet cafe and one at the Babel Tower.  The physical exhibit included a Mac Mini enclosed in a wire recorder.  The monitor was enclosed in the lid of the wire recorder case.  The headphones were industrial noise reducing headsets with high quality headphone drivers mounted inside to provide isolation from the noise of the exhibit hall.  The entire thing was displayed on cardboard boxes, as was everything in the entire Sceneofest exhibit.
