Like virtually everyone else on the Internet, I enjoy a good chart breaking down my favorite pieces of pop culture into their components, cataloguing and organizing them for easy -- or at least well-designed -- reference. As a result, I tend to be a pretty big fan of the folks over at Pop Chart Lab, who have devoted their considerable graphic skills to doing exactly that. The only problem I've had with them is that their first attempt at organizing the names of Gotham City's population of villains and assorted weirdos had some glaring omissions.
Fortunately for me and that blank spot on my wall, they've corrected that in a second version, and it is amazing. Check it out to see where the names of Arkham and Blackgate's maladjusted miscreants fall, from the Joker (categorized under "Inanimate Objects" and specifically under "Playing cards") to the extremely obscure Gloves (under "Gloves").
