Know of any more alternative desktop managers for Linux?

I’m thinking that the desktop has much more potential than what I’m currently using it for (merely displaying icons of minimized/popular applications and a wallpaper), so I was wondering if there are any alternatives to xfdesktop or Nautilus’s desktop management that are really innovative. Preferably not what’s in KDE 4 since I’d need to install a lot of dependencies for that (I’m using Xfce).

Note: I’m referring to desktop managers, like xfdesktop, not desktop environments.
