Kaitlyn Hova and her husband, cofounders of Hova Labs, have recently created the Hovalin, a 3D printable acoustic violin. Last December at “The Long Conversation” event at the Smithsonian Arts & Industries Building, Hova performed on a Hovalin while colorful lights seeped through its transparent structure. The colors represented what Hova experiences with synesthesia, a neurological condition in which one sense (in this case hearing) stimulates another sense (in this case sight).
