Do you know that annoying buzzing sound that comes from stereo speakers when a cellphone rings? That noise in the speakers is interference, and it is audible evidence of the electronic field that emanates from your cell phone. Cell Phone Disco, a project by Auke Touwslager and Ursula Lavrencic, visualizes this electromagnetic interference. The installation itself is a large surface that covers a wall with several thousand red lights, when you make or receive a phone call in the vicinity of the installation the lights react. “It’s not about what you can do with your phone, but what your phone can do with you,” suggested Lavrencic.
