Spam Mimic
http://www.spammimic.com/

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.
