Here is a neat tool for the paranoid or clandestine-minded user. While there are several quality encryption tools available, encrypted email is easily recognized as such. This tool encodes your message as innocent-appearing spam, which many believe the government-run Echelon and Carnivore email reading systems ignore. At present, the site is more of a diversion than an every day tool, as users can only encode and decode short messages through the interface at the site. Still, it's pretty nifty, and a plug-in may be developed in the future.
