Where can I find free Icons? [closed]

Pinvoke.com has two quite nice icon sets. Famfamfam as well.

All licensed unter CC-By.

I've used Iconfinder a few times. It indexes lots of icon sets by keywords, you can limit the search by the size of the icon, and it displays the license for each icon/set (and you can filter out those that aren't allowed for commercial use, if necessary).

I love fatcow. Silk and Tango ain't half bad.

The Tango Project has of course a nice variety of different icons.
