Vidalia is a GUI for the Tor software. Using Vidalia, you can start and stop the Tor software, view its status at a glance, and monitor bandwidth usage. Vidalia also makes it easy to contribute to the Tor network by helping you set up and manage your own relay. This requires qt4 and tor (both available at SlackBuilds.org). See README.SBo (which is also installed with the package documentation) for some configuration hints.
