Diagona Icons Pack 1.0Website: Pinvoke Download: Diagona Icons Pack
The Diagona Icons Pack contains nearly 200 icons in both 10x10 and 16x16 pixel sizes, PNG format. This is one of my personal favorites as the icons are very clear and well designed for their small size. Diagona icons were created by Yusuke Kamiyamane from Pinvoke. If you use these icons you must link back to the authors site or choose to pay for a royalty free license. Either way you can't go wrong.

FamFamFam SilkWebsite: FamFamFam Download: Silk
Probably the most well known icons sets out there Mark James of FamFamFam gives us over 700 16x16 pixel icons in a "strokably-soft" PNG format as put by the author. This was the first icon set that I discovered which opened me to the world of generosity that lives in the open source design community. Silk contains icons for practically every category you can think of.

More goodness from Mark James of FamFamFam. Mini gives us 144 icons, 16x16 pixels in size, GIF format. Quality work, much like the Silk package.
Sweetie BasePackWebsite: Sublink.ca Download: Sweetie BasePack v3
Described as "Cute and clear icons", Joseph North of Sublink created the Sweetie BasePack set which contains 182 icons in varying sizes, PNG format. The creator of these icons accurately described them when he said they were clear, but as far as being cute...I would say they are more on the professional side. Definitely a nice set of icons to have.
