Ever wished you could see the electromagnetic spectrum of radio frequency? Well... while can't, we can try the next best thing, using lightpainting to reveal a WiFi signal strength across a city.
Amazing how you get very weird patterns in places you'd least expect it, and helping understand why we often have frustrations trying to have a good WiFi signal on a particular spot... but moving just a step in either direction fixes it.
Not I suddently feel the urge to WiFi lightpaint my entire home, in order to see how my wireless network actually looks like! :)
