Our World Today: Images reveal how wireless networks sweep and surround us and How dangerous it is
A student has produced a series of vivid photographs that reveal what the networks that keep us connected to the web look like.
The images, created by Luis Hernan from Newcastle University, show spectres of Wi-Fi sweeping and swirling around in bright beams.
They were produced as part of Hernan’s Digital Ethereal project, which aims to bring the invisible world around us to life.
HOW THE PHOTOS WERE TAKEN
Student Luis Hernan created the photographs using a custom-made instrument designed to reveal them.
It scans continuously for wireless networks, and transforms the signal strength to colour LEDs.
The results are multi-coloured streaks of light which twirl and wrap in spaces, showing how they surround objects and people.
Hernan has also created an app which can be downloaded for free, for Android devices called Kirlian, which allows people to see the strength of Wi-Fi around them.
