It’s hard to believe that the thing we are always surrounded by, the Wi-Fi signals, can look so creepy like this.
Luis Hernan is an artist that has been so curious about finding a way to show the wireless which is around us and how it changes.
He did architecture, computer science and design; but his interest made him to be a PhD candidate at Newcastle University to make the invisible visible.
Firstly, what he did was a device called Kirilian which measure the strength of Wi-Fi signals and translates it to different colors that lights up based on the strength of signals.
His project Digital Ethereal includes a system that turns signals into certain beautiful trails of light. So red color means the strongest signals and blue the “weakest”.
Then he photographed these ghostlike movements using his long-exposure photography. And the results documented are so colorful.
The different shapes are captured by moving the device in different ways.
Recently, in his exhibition, he also allowed people to see the strength of signals changing constantly by hanging up plenty of smartphones while running an Android app based on the Kirilian Device.
And here is yet another interesting thing about this app, it also emits various sounds when the display takes a change in color.
"I was very curious about this idea of the invisible signals that surround us all the time so I wanted to explore that," Hernan told Business Insider. "I was really interested in how they would look if we were able to see them."
“Close the wrong door, and the bedroom becomes a dead spot for wireless.”
