Official Seal

Here's a fun website:
http://www.says-it.com/seal/index.php
It lets you create an "official" seal type logo using some clip art and some color sets (you can change the colors). Just type in the top and the bottom, set your preferences and hit the "go" button and in a matter of seconds it generates a seal that you can then copy (on a mac just drag and drop, PC = Right click) to your desktop, use on a website, etc...
