KDE is a desktop environment for UNIX and Linux that runs on top of XFree. In my opinion, the environment and it's software packages are the very best UNIX / Linux desktop environment / software out there.

Enter Ranger Rick, who is in charge of maintaining the Mac version of KDE. Basically, he maintains a version of KDE that runs on Darwin, Mac OS X's back end UNIX. He's got another project, too. He's porting KDE to OS X so that it runs natively. In other words, no XFree.

Now the software is in super alpha mode, which is my way of saying that it isn't even in alpha mode. Ranger Rick has made the software available to curious parties out of the goodness of his heart, and should all be thanking him! Here he writes that he has just updated the binaries for it, and also lists that you can get it here and read the FAQ here.

I haven't had a big chance to play with it yet, but I did install it via webdav last night, and it does run. It took several hours due to it only being on one server and that server, no doubt, being very busy. But this is a wonderful thing! I just had to share.
