Nice set of icons but this is what the author says.
These icons are for personal use only. You can’t use these icons on personal website, software, prints, or any other place without permission from StudioTwentyEight.
Ya right….good luck with that 
Huge set of useable icons that would look great on any site. 150 png icons.
Another great series of Blend icons. This time there’s more…A LOT MORE and they’re in color too!
This is without one of the most amazing free sets of icons that I have come accross. They are very high quality and realistic. There are a ton of apple related and general hardware related icons in this set. Tons of cameras too!
This is what the author had to say:
This is a preview of my coming set of the maxium quality / realism icons I´m able to do. There is 3 icons, becouse this is the preview, not the full release, heh. So, a little taste of whats to come. ; )
Very interesting and unique set of icons that seems to focus on earth elemets.
Another great set of free icons released by Smashingmagazine! Maybe we’ll get one of our sets up there some day!
The set contains 49 free vector icons including PSD which can be useful for both corporate and personal setting. You can use the set for free — without any restrictions whatsoever.
The icons are available in the .png-format in the resolution 128×128px. 100% pure shape-based layered PSDs are also included in the package. This icon set was designed by Deziner Folio especially for Smashing Magazine and its readers.
What this set lacks in quantity, it makes up for in quality. Very hi resolution set of icons in png and ico format.
This is a spin-off of my Front Row Realistic Skin for mac [link] and I basically made .ICO files out of the mac skin for vista users.
