NYSSA has released a free RSS Icon set which sports more of a 3D look than most normal RSS icons. They are available in PNG format and look good on either a dark or light colored background. Each icon is 139X139 in size which should compliment most modern site designs.

Zeusbox studio has released it’s second set of feedicons. The first set which I wrote about here ( Zeusbox Releases Free FeedIcon Set ) ended up becoming a big hit as according to Zeusbox Studio, the pack was downloaded thousands of times. Version 2 contains more than 10 new icons and is filed under the Creative Commons Attribution-No Derivative Work By the way, they are also free.
