Eric Coquin Poirier is a Québécois musician and inventor of musical instruments. He's especially fond of modifying accordions, guitars, and harmonicas to create one-man bands or instruments for people with disabilities.
With the harp reactor, Poirier is going far beyond modifying pre-existing instruments into devising an original invention. This instrument, much of which appears to be 3D printed, combines several harmonicas with a bellows similar to what you might find on a concertina.
In this video, Poirier puts his invention to the test by performing Michael Jackson's "Beat It."
