Wifi signal visualised with light painting

We are surrounded by invisible Wifi networks everywhere we go. What would it look like if these were visualised?

 

The series of images in this video were shot using  a specially designed pole with 80 bulbs that turned off and on depending on the signal strength of the WiFi in the area. It’s a really interesting concept which is the result of a collaboration between Touch, a research project that investigates Near Field Communications and a London design company called Berg.

If you’re interested in the specifics of how they did this (which includes a lot of technical information that I’m not really all that sure of), check out the teams making of blog post here.
