CrystalClear Interface (CCI) is a powerful system add-on that lets you customize certain aspects of the Mac OS X “Aqua” interface. All of these features are accessed using the CCI Preferences Panel, which you can summon using the keyboard shortcut ⌘-' (command-apostrophe) or by accessing the CCI Global Menu.

• A gorgeous user interface for those who think completely different.
• A fully realized theming tool for customizing your Mac's natural beauty.
• Now includes 11 window styles and four button themes — including the theme from Crystal Black.
• Change your menubar with one of the eight built-in styles.
• Mix and match button themes, menubar styles, window themes, and desktop picture all at once... or individually.
• A great solution for eliminating Window Clutter and helping you focus on the task at hand.
• And much more.
