Some more recently released Freebies. In fact a simply designed 192 piece set of flat icons.
These icons are supplied with two versions: full color and single color, giving a total of 384 variations. The download (see below image for the link) kindly includes .ai, .eps, .pdf, and .png (sized in 64px and 128px). The preview image shows the full set in both styles.
Given the designer’s mission to create ‘the best collection of Open Source graphics on the web’, this icon set is completely free and Open Source under the GPL, so you may use them in your personal and commercial projects alike without restriction.
