Ever wondered what WiFi actually looks like?

A bunch of photographs have recently surfaced on the web that demonstrate what WiFi actually looks like. The photographs were created by PhD student Luis Hernan who designed a specific system that scans for wireless networks, creating images where the different strengths of signal can be seen using colored LED lights. The red colors indicate high intensity, and the blue colors indicate low.

Luis explains on his website what his creations are all about: “I believe our interaction with this landscape of electromagnetic signals, described by Antony Dunne as Hertzian Space, can be characterized in the same terms as that with ghosts and spectra. They both are paradoxical entities, whose untypical substance allows them to be an invisible presence. In the same way, they undergo a process of gradual substantiation to become temporarily available to perception. Finally, they both haunt us.

Luis has even developed an app which apparently allows you to view the WiFi signals around you.
