The underground communicators are anonymous networking devices hidden in various locations throughout a city. Connected in an independent Wi-Fi network, they enable their users to leave messages, call a person if she happen to be near one of the other connected devices, create quest-like games or interactive art installations. Even anonymously surfing the internet can be possible if one of the nodes is connected to a public WLAN. The devices are powered either by solar panels mounted on trees or buildings, with the aid of manual cranks or by wind- or water turbines. They use voice-driven OS wherein the users communicate using voice commands or small keyboard attached to it.

The general assumption that mobile technologies represent the future of communications is the basis of many new technological developments. The aim of this project is to explore another possible branch in the communication development. It would allow people who prefer not to carry always mobile devices around, or who don’t want to be continuously tracked to still have access to communications and anonymously participate in independent local networks.
