The folks at the MacGPG project have set up a MacGPG Store for all your crypto-wear needs (someone buy me the clock!) . Says Gordon Worley, the project's admin:

You can buy logo t-shirts, hats, mugs, bags, and other goodies. We offer them to you `at cost'; we earn no profit on them, so you get the lowest price possible.

Check it out and support them - the MacGPG project is pretty damned cool.
