WiFi camera takes "photos" of networks

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?

Pretty cool, i always joke with my brother that i'm so hardcore I can see wi-fi networks maybe one day it will be true :( . They could make special wi fi goggles that would end up looking like you are tripping out

I think the repeating colors show the same SSID in an area like an ir-photograpy at 2.4ghz.

I live in Riga, Latvia. How do I find more info about those folks?

Am I the only person who sees a woman in that projected image?

Each WiFi network creates a full 2D image based on the spatial signal strength, see single network images in the article.

the repeated colors is 3 networks overlaped, read the article and it says that.
