Folder icons are probably related to a theme, which can be changed. LXDE normally comes with Openbox, I believe. I currently have Siduction LXDE installed and that was my first immersion into Siduction. I recently found out from a post by devil that the Xorg edition comes with fluxbox, so I'm seriously considering installing that in place of LXDE. I prefer a window manager only environment over a desktop environment, even something as light as LXDE.
