It’s really fascinating when a designer is able to make paper so much more than a visual instrument for their message. Katharina Hölzl did just that when she designed these music box business cards for Ritornell. Ritornell’s business cards are inspired by the project’s improvised concerts that evoke a lively atmosphere by the combination of filigree electronics with playful timbres of diverse acoustic instruments and utensils such as egg whisks, toilet brushes, chopsticks or sewing needles. Nine micro compositions consisting of circles, triangles and Ritornell’s contact information were laser cut into long stripes of music box paper. The stripes could be collectively played as a long composition or separated into individual cards that could be handed out, allowing the recipient to have a piece of the composition. Before handing out the cards to interested addressees, each individual subdivision is played back via an especially designed musical box – thus providing every business card receiver with a tailor made musical experience. Amazing! Right?
