Here’s one that stood out at the Chip Shop.
Created for a bespoke tailor by graphic designer Greg Healy (broken link removed, 2014). Creative, appropriate, inexpensive (you could finish those yourself with a craft knife).
Using laser assisted milling, nine micro compositions consisting of circles, triangles and Ritornell’s contact info were applied to a musicbox paper stripe. Before handing the “cards” to anyone interested, each individual subdivision is played back through a specially designed musical box — everyone who gets the card hears some tailor made music.
