I have been adding icons to the law library website, to make it easier to spot what you are trying to find. Unfortunately, with no artistic training or talent, I sometimes make icons that are difficult to interpret. But I don't want to violate copyright law, so I try to make my own.
Then I found famfamfam.com, where Mark James makes his free icons available under a Creative Commons attribution license. I have replaced a couple of the more ambiguous icons on our home page with famfamfam icons. Thanks, Mark.
