I love FAMFAMFAM. You see it everywhere on the internet, mostly because: it is sooooo good. But it is also very very out of date (read: has not been updated since March 2006 – so over three years now) hence quite limiting. I have tried contacting Mark James on several occasions but to no avail. I’d love an update, I’d love little Twitter and Skype icons, I’d love GUI icons, I’d love an up-to-date set of icons that would suit our developing needs. And I think I found it!
It is of japanese origin. It is updated often! It contains more icons than FAMFAMFAM. It has a shadow AND a non-shadow version. And it is called Fugue (www.pinvoke.com) 
16×16 pixel PNG icons that seem to be the new FAMFAMFAM immediately striked me. 2037 reasons to look into DocuView’s CSS again Than you, Yusuke Kamiyamane.
BTW – whilst you’re at Yusuke’s website, do check out the free fonts and the Diagona icons he offers too!
Nice post. Great alternative ot famfamfam, which although brillaint, are everywhere.
Thank you Chris, hope you find them as useful as we have! It’s been six months since I’ve published this article and Fugue (Pinvoke) icons still are the most comprehensive set of UI/software mini-graphics out there. Happy to spread the word!
All the best,
Martin
This is exactly what I was looking for! Thanks so much for sharing this in the same terms I was searching for (gotta love Google) while looking for an alternative to the Silk icon set. Fugue looks great!
Updated – Yusuke Kamiyamane now started working on 32×32 icons as well, with updates as often as four times a month. A year into this article Fugue Icons are the only FAMFAMFAM alternative I have found so far, and well worth paying the commercial license for!
