Torberry (https://code.google.com/p/torberry/) is a Raspbian-based Linux distribution for Raspberry Pi, designed to route all your Internet traffic through the Tor network.
According to the Tor website, Tor can be defined as follows:
"Tor is free software and an open network that helps you defend against traffic analysis, a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security."
Torberry is designed to be installed onto your Raspberry Pi and serve as a Tor transparent proxy that routes all your TCP and DNS traffic through the Tor network. This means that it is harder for someone to find your location.
