The Symphony in D Minor is a joint project by Patrick Gallagher and Chris Klapper.
About the project:
Symphony in D Minor is an interactive sound and video installation on an epic scale. A thunderstorm contained within a series of large hand cast resin sculptures, each individual form is a unique instrument hanging 40 feet from the ceiling.
Suspended just within reach and activated by touch, the viewer sets the symphony in motion by pushing the forms through the air to trigger the various sound elements of the storm.
Like giant illuminated pendulums each sculpture radiates video projections that in their dormant state display abstractions of water droplets and slow moving clouds. As the sensors detect movement different ranges initiate more visual elements of the storm. Once activated, the form then shifts to a swirling torrent of clouds.
