This totally genius creation was thought up by Austrian designer Katharina Holzl¬†for musical duo Ritornell. When you run the perforated pieces through the accompanying music box, you hear music; I’m seriously blown away right now. Even the band is pretty great! They have a very jazzy, cinematic sound, fittingly reminiscent of The Cinematic Orchestra. Stream Ritornell’s latest album here, and watch a demonstration of the business card down below. via
