Linux desktop icon theme (Gtk, Gnome3, Xfce4) by Sora-Meliae
This is an icon-theme maintained with Xfce in mind, but it supports other desktops like Gnome3 as well.
This repository holds Matrilineare version 3 from Deviant Art: http://sora-meliae.deviantart.com/art/Matrilineare-version-0-3-321379531
Author is DeviantArt artist Sora-Meliae (Andrea Soragna). She (or he) hasn't answer any question at her DeviantArt profile since 2013 and I couldn't find her anywhere else on Internet, so I decided to make a backup ot her great icon theme at Github.
