This is a new KDE Start menu and it totally rocks.
OpenSUSE 10.2 will have a redesigned KDE start menu created by the KDE and usability team at SUSE, after doing usability testing with other start menus. Now they have a working prototype, code-named 'Kickoff' (started during world soccer championship, obviously), which is currently being tested with real users in the SUSE usability lab.
You can see new menu here or see sneak preview mpg file. (via OsNews)
