IMMATERIALS: LIGHT PAINTING WIFI
Timo Arnall | JØrn Knutsen | Einer Sneve Martinussen
Immaterials was a photography project started in 2009. It explores the idea of capturing what wifi actually looks like in an urban setting. The project does this by setting up a long exposure wile someone holding a tall rod with LED lights that pick up on the strength of the wifi signal walks through the scene.
The lighting display was created using a four-meter tall wood support structure with 80 LED lights attached to it. The lights respond to Received Signal Strength (RSSI). When moving through a space with this device in combination with long-exposure photography the device creates what looks like a graph or section of the strength of a wifi signal forthat specific spot and time, and what becomes really fascinating is when this experiment is repeated in the same spot because the photographs show the almost rippling cloud like quality of wifi.
