Visible Wi-Fi signals

Now we can see the invisible! I always wondered what those Wireless Signals looked like as they zoomed through our bodies. Steve. 

the artists placed a camera nearby as they took a Wi-Fi-equipped rod with 80 LEDs to various locations at nighttime in the Oslo borough of Grunerlokka. The lights illuminate at varying levels depending on signal reach.
