The Theremin Inspectors
Created by Sean McDonald and Alex Hornbake, The Theremin Inspectors is a mixed-reality visualization experience that enables people to actually see the electromagnetic fields that they interact with every day. Using a theremin—an electronic instrument you play by moving your hands through open space rather than touching controls—the exhibit highlights how the human body can interact with electromagnetic energy to make music. The key feature of the exhibit is a “mixed-reality” video system that shows the performer live in real time, with a data visualization effect that shows an imaginative rendering of the cloud of electromagnetic energy around the instrument.
