|Periodic Table of Storytelling by Dawn Paladin/ComputerSherpa|
You can find a larger version here. I really like how he used the concept behind a periodic table of elements, rather than being too strictly literal and arbitrarily forcing their categorized tropes into the precise formation of the periodic table. Each element has a one to three character acronym and little description to describe a trope, and they are grouped in periodic table-like families. Also, I'm charmed that he's listed Tbl Parodic Table of the Elements as one of the (pale yellow) Metatropes. Ooh, self-referentiallity! Further, the atomic number is replaced by 'Popularity in kilowicks' or the number of thousands of links to its page within the wiki. At the bottom he explains how the elements bond together in various stories (only two of which I know.... so I can't really tell is there is anything more than a design choice behind the nature of the drawn bonds), much like elements in a chemical compound. This is a a Parodic Table of the Elements made with some care and love.
