Media repository Wikimedia Commons has a collection of 300 dazzling 3D icons, all of them free to use under Creative Commons licensing.

The Crystal Clear collection is divided into sections to simplify your perusal: Applications, Devices, File Systems, KDM and MIME-Types. Each icon measures 32×32 pixels and comes in the PNG format. They’re an impressive lot, perfect for site builders who want to add dashes of style and color. Alas, there’s no way to download the entire batch; you have to grab each icon individually. But that’s a small price to pay for such attractive freebies.
