The Periodic Table of the Elements of Middle Earth was inspired by a discussion on Tolkien_Slash. The elements and their associations were matched up with help from the folks on that list.
The first link has a miniature version of the full Table and an explanation of the more obscure abbreviation/element pairings. The other four each have one quarter of the full-sized version and show a lot more detail. If you want your own copy, each picture SHOULD be the right size for a standard printer to handle if you right-click the pic, save it to your computer (eliminates the extra web stuff that would otherwise mess up the frame), and change your printer's source settings from Portrait to Landscape.
