Jul 2006: Phase two is over, and brought us three fine interface projects: Vidalia, Torbutton, and TorK. Thank you to each of you who participated. The GUI competition is now ended — but don't let that stop you from helping out!

Feb 2006: The first design phase is over, and we have two winners. The CMU Usable Privacy and Security Laboratory won "Best Overall," and the April3rd team won "Most Aesthetically Pleasing." Feel free to use their ideas if you like them.

Dec 2005: We're excited to have just added Edward Tufte and Bruce Schneier to our already impressive list of judges. And don't forget the free Tor T-shirt for every submission!

Tor: GUI Competition Overview

Tor is a decentralized network of computers on the Internet that increases privacy in Web browsing, instant messaging, and other applications. We estimate there are some 200,000 Tor users currently, routing their traffic through about 500 volunteer Tor servers on six continents. However, Tor's current user interface approach — running as a service in the background — does a poor job of communicating network status and security levels to the user.

The Tor project, affiliated with the Electronic Frontier Foundation, is running a GUI competition to develop a vision of how Tor can work in a user's everyday anonymous browsing experience. Some of the challenges include how to make alerts and error conditions visible on screen; how to let the user configure Tor to use or avoid certain routes or nodes; how to learn about the current state of a Tor connection, including which servers it uses; and how to find out whether (and which) applications are using Tor safely.


Submitters for phase two will produce a work of Open Source Software that will provide a user interface to the Tor system, perhaps by way of the Tor Controller Protocol.

We are looking for a vision of how Tor can work in a user's everyday anonymous browsing experience.

We're interested to see submissions that don't achieve all of the above goals -- if it's useful to Tor or Tor users in any way, please submit it!
