Kirill Grouchnikov released the Flamingo component suite 4.0, an open source (BSD license) "Swing implementation of the Office 2007 ribbon container and related components. The components have consistent visuals under the existing core and third-party look-and-feels, respect the DPI settings of the user desktop and follow the core Swing guidelines in the external APIs and the internal implementation details." Version 4.0 adds an application menu, title bar, key tips, rich tooltips, and more. Java 6 or later is required.
