Eindhoven-based designer Richard Vijgen has created a tapestry from thermochromic yarn that makes invisible Wi-Fi signals created by cellphones, printers and smart devices visible.
A controller linked to the tapestry listens to all traffic across 13 channels of the 2.4GHz Wi-Fi spectrum. When it detects a transfer, it converts the wireless activity into an electric current that is delivered to the tapestry via a series of wires.
The thermal elements embedded in the tapestry convert the current to heat, which causes the thermochromic yarns to change colour.
Once activated, the fibres turn from midnight blue to a silvery white and back again.
