This Icon Set is from the beginning composed out of bits and parts of other icon sets which I thought went well hand in hand.
A lot has been tweaked, not much is in its original state and I have also made icons from scratch for this theme In order to fill out some gaps.
The system preferences-icons is an example of icons I've made from scratch.
This theme is suited for Elementary OS Luna, I give no gurarantees for how complete it will be on other DEs.
