Since the dawn of the radio, over a century ago, there has been buzz about the invisible rays that make our tech go ’round… and what they’re doing to our bodies, and as our lives become more wireless, the myths and rumors presumably expand into an ever denser unseen web. Perhaps the most unsettling thing about those “invisible killers" is that they are, indeed, invisible. But add another layer to the equation and you’ll discover that those unseen signals are actually beautiful pieces of art (not that that’ll make you feel better about what they may or may not be doing to your health). Newcastle University’s Luis Hernan is giving us a peek into the concealed world of wireless signals with his project, Digital Ethereal.
Using what’s being described around the blogosphere as “a piece of equipment that translates the strength of the Wi-fi signal into colors" (blue being the strongest and red coming in as the weakest—like flames in a fire), Hernan captures time-lapsed shots of these waves at work. That description is about as vague as the ghost-hunting tools we see paranormal scientists toting around on the sci-fi channel—which actually makes sense considering Hernan compares the waves to ghosts, thanks to their invisible qualities.
