Nice new icon sets for Horde
Daniel Dembach has created a really nice icon set for Horde based on the FamFamFam silk icons, and a Tango icon set has been uploaded to our ticket system.
Daniel Dembach has created an icon set with the FamFamFam silk icons that can be downloaded from his blog.
Another user has created an icon set based on the Tango icons. The Tango Desktop Project is an effort to create consistent GUIs independent from the window manager of choice. It's part of the freedesktop initiative, but doesn't really seem to have gone off yet.
At least the Tango icons are planned to be released as part of a new skin called Rhea. I don't know if Daniel is going to release a complete theme too, but the screen shot doesn't look like one of the official Horde themes.
