Cowabunga, Dude
For you X Window manager fiends out there comes the latest update to Waimea (Hawaiian, noun, pronounced why-may-uh and meaning reddish-brown river in English, referring to the famous surfing spot on the island of O'ahu). Waimea uses the cairo graphics library to render a spiffy desktop. Unfortunately, there's not a whole lot there at the website but I guess if you know what a X Windows manager is you can figure out how to use it. YMMV.
Aloha!
