160 Beautifully-Crafted & Free PSD Icons
You will remember 365psd, a lovely website -featured at WRD before- that publishes one free PSD each day.
Recently, they have released a new freebie which is an awesome set of tiny icons.
As expected, they are in PSD format, 30*30px by default and comes in a very well organized PSD file where each item is placed inside a layer group.
The set is so suitable to be used in web apps considering it has most of the commonly-used web app icons.
