Patrick Gallagher and Chris Kappler's Symphony in D Minor is a recent, unusual exhibition containing an interactive video and sound installation, where the experience of a thunderstorm is re-created. In order to do so, the two built cylindrical sculptures which hang 40 feet from the ceiling. These sculptures contain a number of sensors that create a variety of weather patterns according to the movement underneath them. Whether you're in for a storm or just want to move around, Philadelphia's got the installation for you.
