When xkcd creator Randall Munroe first posted a new installment of his webcomic titled “Time” on March 25, it looked deceptively simple: a picture of two black and white stick figures, a man and a woman, sitting wordlessly on the ground. There was no story, no punchline, no words. 30 minutes later, the image changed; the figures shifted slightly. And they continued to change every half-hour for the next week–and every hour for months after that–slowly coalescing into a story as the two characters discovered disturbing changes in the landscape around them, and set out on an epic, time-lapsed journey to discover the truth about what was happening to their world.
