In 1939, Semyon Kirlian discovered how to capture the electrical field—or aura—surrounding living things using photography. To create these images, he sent an electric current through an object to capture electrical coronal discharge images on a photographic plate.
These pictures result from describing the space through a performance with the Kirlian Device, which transforms signal strength in light color (reds for high intensity, blues for low intensity).
Coupled with long exposure photography, it is possible to register the changing qualities of wireless networks.
The Kirlian Device is an instrument designed to reveal qualities of wireless networks.
