Randal Monroe began publication of XKCD #1190 at midnight EDT on March 25, 2013, with the comic's image updating every 30 minutes until March 30, when they began to change every hour, lasting for over four months. The images constitute time lapse frames of a story, with the mouseover text originally reading "Wait for it.", later changed "RUN." and changed again to "The end." on July 26. Matthew Walker compiled all the images into this video.
