This is an iconset for Mac OSX. Use it only on that operative system. It includes 21 original icons.
It's a new flavour of the original Noia icons, this time they are an alternative to some of the usual icons. Note about the names: the Noia icons are available for the 3 major platforms (Mac OSX / Windows XP / KDE-Gnome); some of the icons will use different names for very different kind of apps, deppending the platform.
