Ben Walding has put together a page that contains all the icons contained in the Eclipse CVS repository. It’s a handy resource for finding just the right icon. They’re all released under the EPL, so you can actually reuse the icons (subject to the terms of the licence).
See here for a discussion of the page, including a description of how it was/is generated. Click here for the icons themselves.
You may recogize a few of these icons from the eclipse.org website. I know that Denis uses them on some of his pages.
