Long ago I wrote about free Russian style icon set from company VisualPharm. But they have even more free icons. Check them here (or click on image below): http://www.visualpharm.com/free_icons.html
But it’s not all!
They’we designed and released for free an omni-growing set of free metro style icons:

And it’s even more — people decide, which icons they draw next. Here’s how it works:
1. People propose icons.
2. People vote.
3. VisualPharm draws the most voted ones, 3 a day.
And everything is free. They do this partly for fun, partly to speed up work for their own projects (creating only missing icons), partly for self-promotion. Check it all out here: http://icons8.com.
