This is nothing more than a simple mod of DanRabbit's awesome Humanity icons to my own liking. I've changed the trash icon to the one from GNOME-Colors, and added transparency for the 22px high ones. With this setting the trash applet on the panels look more consistent with the new grey status icons of Humanity. (Yeah, I like the trash icon next to the clock at the top.)
The other things I added are the WINE related icons. (They are from GNOME-Colors set as well.)
If anyone has any more idea how to mod this set please feel free to comment.
And of course I thank the original creators of both icon sets for the drawing of these awesome icons.
