Well with The Incredibles superheroes seem to be in the air lateley.
This is a fun collage project that will hopefully grow. And here is a goofy McSweeneys story with a lot of inside jokes. And this is a weird little project that I don't quite know how to explain (you need acrobat reader for it). For a literary context, here's Shaviro's Doom Patrols, a set of essays that looks at comic books authors and characters alongside experimental artists and authors. It's several years old, but a fun read and still relevant.
