Silk Icons: Here’s a really great set of free icons (a very small subset displayed above). We’ve talked about stock icons before (that article is top 10 on Google for “stock icons”), but these look just about as good and don’t cost a thing.
“Silk” is a smooth, free icon set, containing over 700 16-by-16 pixel icons in strokably-soft PNG format. Containing a large variety of icons, you’re sure to find something that tickles your fancy. And all for a low low price of $0.00. You can’t say fairer than that.
They have a Creative Commons license, even. Via Lifehacker.
