'Change the Tune'

 Michael Robbinson at London creative shop Agency Republic has designed one of the coolest posters I have ever seen. The poster is built up with knock sensors, wires, a plug socket and Audrino Nano and through some form of crazy technology if you throw something at the poster it changes song. Since the agency plays music via Spotify over the sound system the ‘Change the Tune’ poster has access to millions of songs for free. Very cool stuff.
