A Periodic Table for Visualisation Methods

Everyone student knows what the Periodic Table of Elements is. What if the style of the Periodic Table is used for other things? On Visual-Literacy.org, there is an attempt to place the method of visualising ideas, such as tables, timelines, concept maps in a Periodic Table format. When you mouse over the elements in this Periodic Table for Visualisation Methods, an example will appear. Also, you can find a paper (in PDF format) that describe the table. Really useful and interesting stuff if you're interested in methods to do with presentation of ideas.
