The Atlantic magazine has a "special report" in their May issue titled How Genius Works, which focuses on how various creative types go from vague idea to first draft, and one of their chosen geniuses is Ben Katchor, who was the first cartoonist to win a McArthur Fellowship (which I guess makes him a certified genius). Katchor presents a three-picture slideshow with a bit of commentary about what inspires him and how he works, which is more of an insight into his particular working process than a blueprint for the rest of us—but still makes interesting reading.
