Great creative commons licensed icon font. I can see this really coming in handy on some future side projects.
While on the subject, if you’re in the market for web page icons (with flat colors and no fancy treatments) bundling them in a single font is often the best way to go. Fonts are vector based, making them infinitely scaleable for multi-resolution displays and you get a single http request to pull in the full icon list. This really played out well with the Climacons Font on my Blue Drop web app.
