WiFi camera takes "photos" of networks

Cyrus Farivar

Those good folks across the pond sometimes amaze us, and other times they just plain confuse us. From what we can gather, this cantenna (made with wasabi cans -- nice touch!) scans for WiFi networks in its vicinity and takes "snapshots" of those networks, and then translates that data into a visual representation -- a color SSID. Once the data stack is large enough, all those SSIDs get project on the wall, but if each SSID gets its own color, then why do we see repeating colors in this photo? Maybe if you're in the Riga, Latvia area sometime in the next couple weeks you can fill us in as to how this exactly this sucker works. Anyway, it sure livens up a room, don't you think?
