Cell Phone Disco

Cell Phone Disco is an art installation which visualizes the electromagnetic field of a mobile phone. Installation participants are able to see the ‘invisible body’ of their mobile.
It incorporates several thousand flashing cells which individually consist of one or more LEDs, battery and a sensor. When the sensor detects EM waves it sets off the LEDs to flash for a couple of seconds. It’s a wonderful result of using off-the-shelf technology to illustrate the invisible.
There are two variations to Cell Phone Disco. One, entitled Mobile AUra, allows a participant to walk around the installation and watch the ‘invisible body” follow. The other, Mobile Drawing, uses less sensitive cells to create a canvas for an inkless marker. Moving the phone close to the cells leaves a trace of light, an electromagnetic drawing.
