This probably isn't what you had in mind, but I was threatening to do a Grateful Dead, tie dye sort of paint job on an old Nikon FG (earl momus will paint ANY camera for only $19.95!) but I sold the model. It still interests me, lord knows why, because when you actually use the camera, who sees it?
Pretty sure an FG is metal that looks and feels more like plastic. Nice little cameras, very light and small, Mickey Mouse plastic, double jointed film advance lever is a liability though. They break often, as do the complex electronics that Nikon jammed into such a small package.
