Light Painting WiFi

WiFi networks are all around us but we never see them. The only way we know they're actually there is by looking for the little icons on our phones or computers.
This great little project temporarily changes that by visualising the flow of WiFi signal strength in urban spaces. I really like the way it explores and reveals the invisible nature of online networks by turning them into something very analog and visible.

It's done by using a light painting technique and capturing it in long exposure photographs. Practically it means moving a four metre tall measuring rod fitted with 80 light points though urban spaces while photographing.
