I'm pleased to announce the Silverlight 2 version Wikipedia Thesaurus Visualizer. It now provides much more rich user interface and supports many modern browsers (IE, Firefox, Safari and Chrome!) on both Windows XP/Vista and Mac OS X. Furthermore, we implemented many additional features in this release. Have a look our at our Web site for more detailed information.
