From the Hey-Neat dept.:
TorPark is the intersection of two relatively recent free software developments: portable Firefox and the onion router. Just like the chocolate and peanut butter of the old Reese's ads, they taste better together. With TorPark on a USB flash drive, you can bring the power and flexibility of Firefox with you when you travel -- and count on Tor to keep your browsing anonymous and secure at the same time.

The current TorPark package (1.5.0.2) is available as a 5.6MB self-extracting Windows archive, localized for more than 30 languages. Expand the archive and inside you will find a folder that you can copy directly onto any rewriteable medium (flash drive, hard drive, etc.). TorPark will not run from a CD, since it must write to a local directory.
