I found a few programs at a place called Glenn's Eclectic Freeware

Personal like is for Desktop Info. Bit of a HUD, this one. Everything's editable, down to the colors, screen position, what system categories are shown, etc. All changes are made from within an .ini file. The desktop display can be made draggable and right-clickable, again, through the .ini file.
