Nuvola icon repository Being interested by GUI makes me look for the most attractive icons for applications .. and I found that Nuvola is a nice source of high quality icons .. works well with java applications even on Windows.

Too bad he doesn’t have any plan to create a windows icon pack also. :((
You can still use the icon set on windows .. I did it and I’m not a second worried about the quality of my GUI because of that 🙂
