How does one visually communicate the world of invisible Wifi networks in urban space? This project provides a solution by using light painting to show Wifi signal strength in long-exposure photographs. A whole unperceived word suddenly comes to light (excuse the pun) that we unconsciously walk through and live in every day! Seeing this makes me wonder about all the other waves, signals and networks that remain unseen. Do they affect us at all? Do our bodies unconsciously sense them? It just shows how little we know of even our immediate surroundings. Enjoy!
