Today Jovoto comes along with something very useful: a large collection of recently released free icon-sets.
The whole collection has been published already in june by smashingmagazine, but I think it´s still newsworthy. Below I show you some examples, the original article with all icon-sets and links you´ll find here.
(If you are looking for more also check this helpful tool: the icon-finder)
