Immaterials is part of the Touch project, based at the Oslo School of Architecture and Design. The project explores the invisible terrain of WiFi networks in urban spaces by light painting signal strength in long-exposure photographs. A four-meter tall measuring rod with 80 points of light reveals cross-sections through WiFi networks using a photographic technique they call light-painting.
While we were mapping out tiny RFID fields, we wondered what it would be like to apply the light painting process to larger-scale fields of Bluetooth, WiFi, GSM and 3G.
What if we built huge light painting apparatus that could map out architectural and city-scale networks in the places and spaces they inhabited?
