This is one of those obscure-ish window managers that is just lurking out there needing to be found. There are lots that get no press, and are fantastic and innovative. People often gripe about wanting to lose the WIMP interface, and they don't realize the options ARE out there, and the options go beyond just using CLI.
This is one of those WMs. If you are looking for something that redefines graphic usage, without being clumsy, you should check this out. The author of this WM has obviously put a lot of effort into making it useful. Not only that, a rarity: It is well documented, and docs are available in multiple formats.
I know I've seen the announcements for this WM fly by and I've consistently ignored it because I've never heard of it, what a shame. Now it is my WM of choice.
As the author says, it is kinda like vi, it sounds weird, but once you get the hang of it, watch out!
Well, for right now you can get the source files from debian. They have the raw stuff archived, as well as a debianized patch.
