Vidalia OS X client for Tor tunneling network
Vidalia is a cross-platform GUI for the Tor network, which makes it very easy to anonymize your Mac's TCP activity. The Tor project (which we posted about a long time ago) is a volunteer network designed to foil traffic analysis and thus allow you to cover your tracks online. Basically it bounces your network requests across a number of Tor computers (and back again) so that nobody is able to figure out your actual destination.
This is obviously useful for keeping your identity secret, but it may also allow you to access IP addresses and services that your local network administrator blocks. Now you should think carefully about trying to circumvent such restrictions, as bad things may happen to you if it's discovered. The other big downside is speed. Needless to say if you're bouncing around computers all over the globe before you get to your destination there's going to be some lag. Nonetheless, if you need the anonymity (or if the people you're communicating with need it -- think journalists or whistleblowers) it may be worth it. You may also like to contribute your own computer as a node to help out the network.
Vidalia is open source and a free download. The latest package is marked for Tiger, but it seems to work on Leopard as well. If you're having trouble getting it from the Vidalia project page you can also download it from the Tor project download page. Once you download it, be sure to carefully follow the instructions in the Installation Guide for OS X.
