Simon Elvins is a digital artist and a graduate from MA Communication Art & Design at the RCA. Among many interesting projects in his website is FM Radio Map. The map plots the different locations of FM commercial and pirate radio stations within London, made site specific by connecting only the stations that can be received in that location. This is done by drawing power lines in pencil on the back of the map, which conducts electricity from the radio to the front of the poster. Placing a metal pushpin onto each point enables us to listen to the sound broadcast live from that location.So the map is not only a representation of the physical locations of radio stations, but also an audible interface which can be navigated through sound.
