Your MacBook Has a Force Field. This Is What It Looks Like
Radiating from its hard drive, optical drive and tiny motors is a force field of magnetic and electric charges. Called an electromagnetic field, it's invisible to the human eye-usually. But a recent project from two designers at the Copenhagen Institute of Interaction Design have made the invisible visible. Luke Sturgeon and Shamik Ray have created light paintings from the EMFs emitting from our everyday electronics. The result are ghoulishly pretty images showing wisps of light floating above a laptop and flowing from a radio's speaker.
