In case you didn't know, our beloved UC applications have new icons associated to them. I looked for these and didn't find them together at the same place, so I decided to share them here.
The Lync logo is 220x220px, the other 2 are 256x256px.
You can save the picture by right clicking on them in your browser.
*UPDATE* : you can find an entire set of Office 2013 icons on DeviantArt (in both PNG as ICO files)
