10 years ago a guy did WiFi signal mapping using a single antenna and a CNC router. https://www.youtube.com/watch?v=aqqEYz38ens

This real time visualization is pretty mind-blowing. Filter by MAC address? Wonder how long this has been used by the usual suspects.

Reminds me of the faraday cage in 'The Conversation'.
