For most of us, the only way we can see the strength of a WiFi network is by the familiar signal icon on any given device. Newcastle University School of Architecture doctorate student Luis Hernan, however, has a different method: spirit photography. He's using the new age-y method of capturing someone's aura via electric coronal discharges -- a Kirlian Device -- with a few geeky augmentations (an Arduino Uno board and WiFi Shield, for example) to illustrate how strong a wireless broadcast is with colors. As Wired notes, these components take account of the nearby signal and convert it into color information that's then beamed onto an LED strip; red being the strongest and blue being weaker sections of the network. To create the pictures like what you see above and at the source, Hernan swung the home-made device around after setting up long-exposure shots with a camera. While we can't know for sure, we'd imagine that something with no signal would look a lot like this.
