Just wanted to share my desktop: I'm using Cillop for my theme, and for Amarok, I'm using Domino to try to replicate Cillop as much as possible. I think it works alright. I'm also using the Glossy Icons, but I'll eventually be using icons lifted from the Gnome icon theme, OSX-itunes. I've also started adding icons from various other places, such as the Tux 'n' Tosh icons.
I'm using Avant Window Navigator and Kwin (with Baghira) to take care of shadows and transparency. Beryl was just eating too much of my limited RAM, Compiz never quite worked, and xcompmgr just never seemed to work right. Kwin also doesn't cause problems with 3D games. Eventually I'm going to make a Kwin theme based on BlendedSmall, which is what I normally use with Metacity, because I just haven't found anything that looks as nice to me.
My main goal is elegance and no clutter. So no desklets or other eye-candy. It's another reason why I didn't use Beryl, because I always left 90% of things turned off on it. Just didn't seem worth it. It's also the reason Firefox has been pretty well trimmed back, and it also has forced me to learn a lot of the keyboard shortcuts. Next up: trying to figure out how to do the same in Thunderbird.
Let me know what you think! I'm pretty happy I got this going--it makes my crappy little Toshiba look like it cost a little more than three-hundred bucks!
