Katharina Hölzl designed very special business cards to recreate this playful sonic universe. With the aid of laser assisted milling, nine micro compositions consisting of circles, triangles and Ritornell’s contact information were applied onto a long musicbox paper stripe. Before handing out the cards to interested adressees, each individual subdivision is played back via an especially designed musical box – thus providing every business card receiver with a tailor made musical experience.

Seems finicky, but it’s a beautiful idea and execution.
