Immaterials: Light painting an invisible landscape

There are invisible landscapes all around us. Every day we live among them, pass through them, we utilize them, yet they remain completely undetected by our naked eye. Timo Arnall, Jørn Knutsen and Einar Sneve Martinussen have ingeniously devised a method to visualize these concealed network within physical space. They built a light stick that responds to Wi-Fi signal strength, walked it through the city revealing with time lapse photography the changes in the transparent atmosphere. I won’t go into detail on how they created the device, you can read all the specifics here. I just love how they found a simple and visually beautiful way to open our eyes to what we cannot see. Makes me wonder what other forces are fluctuating around us that we are unable to detect, and who will come along and reveal them to us.
