Here's an idea.. I imagine many GNU/Linux (although not necessarily only GNU/Linux) users combine various elements from different window managers or desktop environments into what suits them most. For example you could use a panel from GNOME in a KDE (which would sure be a pretty weird combination to some maybe..)
Well, this is where you can post about your creative combinations...
Here's one I find to be pretty elegant. Since I like Xfce, but am still used to having a proper desktop with icons I decided to combine nautilus desktop from GNOME with Xfce.. It's braindead simple actually, as I just have to launch nautilus (without the --no-desktop option) and I'll have my gnome desktop icons within the cool Xfce interface. And it looks awesome.
So what about your cool desktop combinations?
