Amazing Rainbow Ghosts Show How Wi-Fi Signals Are Shaped

Luis Hernan is like a modern day ghost hunter. Only instead of searching for lost souls, he’s looking for the technological apparitions that surround us every day.

In Digital Ethereal, Hernan, a PhD student at Newcastle University’s School of Architecture, has been investigating the invisible wireless infrastructures in order to glean a better understanding about how these wireless systems are designed and how we interact with them.

Digital Ethereal is part art, part industrial design and part technological inquiry. He began by designing a gadget called the Kirlian Device, named after Semyon Davidovich Kirlian, a 20th century scientist who developed the Kirlian photography technique.

This technique, which visualizes electrical coronal discharges, has been used for various scientific purposes, but it’s most commonly associated with paranormal activities like reading auras.
