Mind Your Head by Philip Marston is a simple and playful installed object which the viewer/participator (by wearing the headphones and walking under and around the suspended light) can audibly experience the invisible electromagnetic frequencies which leak and radiate out of an ordinary fluorescent tube light.

The headphones, with an EMF (electromagnetic frequency) pick-up attached, provide a new form of intimate but unnerving physical interaction with an overlooked mundane object, which hopefully highlights our every increasing environmental exposure to man-made electromagnetic fields.
