In the spirit of the thread I thought I would show some of my desktops from WM/DE's that only a few seem to use. Slackware comes stock with Xfce and KDE of course, but it also has Fluxbox, Blackbox, WindowManager, Fvvm, and Twm. Gnome and Enligtenment, at least e16 are pretty much no-brainer add-ons.
So this time I'll show 4 (assuming the forum allows it... if not, one at a time) WindowManager, Blackbox, FluxBox and KDE with a few twists.
On the surface Blackbox and Fluxbox are similar but because Fluxbox has explicit full support of Gnome and Kde it's footprint is bigger so it isn't quite as ridiculously fast as Blackbox.
WindowManager is vastly underrated and even if you only use it's utilities, icons, themes, etc in other DE's it is well worth installing. I have seen the plain Jane Blackbox dressed up to ultimate eye candy via WindowMaker.
The Kde twists depend on 2 simple features - window shading and Eterm.
AFAIK in any distro or DE if you dbl-clk on the title bar the window will roll up and down like a shade. It's faster than "minimize-maximize" or "switch desktop" and can clean up a desktop nicely, In this case XMMS is open with "playlist" and "equalizer" all attached side-by-side and shaded small.
If you like eye candy Eterm has easily controllable size and location parameters as well as backgroun image, font size and color. I wrote a simple script so that eterm would launch with Kde and place it behind the auto-hide taskbar. It is shown with just the title bar showing as the taskbar is up. It's faster that "run" plus you get persistence so any errors or comments show and stay for reference.
PS Flux and Black have some "other" eye candy open just for good measure
