Following a theme of original (or at least, reimagined) audio delivery, artist Jenny Gaskell gave me the brief of delivering audio via retro telephone handset. This was achieved by hacking GPO 746 reproduction phones (red) with a microcontroller & MP3 module – audio is delivered after dialling. The power cord is hidden inside the RJ11 socket.
More can be found out about the work itself here.
