Light painting WiFi
Wireless networks are everywhere these days, creating invisible layers that we cannot see. This unique light painting project seeks to change that by mapping the signal strength of Wifi networks in a variety of environments. The light painting is made using a WIFI signal strength detector and a bar of LED lights. They used a long exposure camera to capture the fluctuations in signal strength as they walked across a street, campus, etc.

WiFi Impressionist
Wifi Impressionist is a field installation that draws electromagnetic landscapes inspired by the cityscapes of William Turner. The work consists of a directional antenna on a pan-tilt mechanism that listens for WiFi signals and builds a three dimensional model of the signals around it. From this model a viewport is selected that defines the perspective and the frame. Signals that are picked up within the frame are visualised as waves emitted from a specific origin and drawn using a mobile plotter. The antenna and the plotter are both mounted on a tripod and can be placed in the field much like a painter would set up his easel. Once positioned and oriented a drawing becomes denser over time depending on the density of networks around it. Wherever there is a WiFi signal, the drawing will eventually fill the frame.
