KateOS 2.2, their gal too!
Kate OS is a multitasking operating system, which brings all that is necessary for: programmers, webmasters, administrators and home users. KateOS is Distrowatch's Featured Distro of the week and Phoronix has the screenshots.
The default desktop environment of Kate OS is the fast XFce desktop with an intriguing theme. Although it might not be to everybody's taste, it makes for a refreshing change from the usual variations of blue that most distributions seem to prefer these days.
And of course, my own review of KateOS 2.1.
