Crystal Black is a theme for Mac OS X "Snow Leopard" that I'm still refining and plan to release eventually. I published a preview of the theme last fall, and a few weeks ago released a Crystal Black theme for iTunes. The skins for both iTunes and CoverSutra will, of course, be included in the full theme once it's out.
One more application-specific Crystal Black theme I plan to release soon will be of interest primarily to web developers: It's a theme for Safari's Web Inspector module. Stay posted for more on that, and for more about Crystal Black as a whole.
Update 4/18/11: The full Crystal Black 1.0 theme is now available from the Crystal Black website.
Installing Crystal Black for CoverSutra
The download contains a little application that installs the Crystal Black theme for CoverSutra. To install, simply doubleclick the application and select "Install." You can also use the app to restore the default CoverSutra theme. To restore, doubleclick the app and select “Uninstall.”
After installing or uninstalling the theme, you'll need to quit and restart CoverSutra for theme theme to take effect.
Also included in the download is a folder containing CoverSutra's default (black) menubar icon, as well as a white alternative for those who use a dark menubar.
