WifiTapestry is a dynamic wall hanging that visualises the wireless activity of a space. The tapestry visualises the ever changing "landscape" of radio frequencies around us. The invisible signals from Cellphones, printers and all kinds of smart devices leave an imprint as they try to negotiate available wireless channels.
A controller listens to all traffic across 13 channels of the 2.4GHz WiFi Spectrum. Whenever data is transmitted on a channel, the controller sends a current to an array of thermal elements embedded in the tapestry, converting data into heat and activating a thermochromic yarn woven into the tapestry. Like a Shroud of Turin, streams of data transmitted through a space appear as visual traces from an invisible dimension that gradually form and dissolve.
