xkcd: Time

About this book

"Time" is the 1,190th strip of Randall Munroe's webcomic xkcd. Beginning with a single frame published at midnight on March 25, 2013, the image was updated periodically (once per hour with a few exceptions) for 123 days, ending on July 26 with a total of 3,099 unique images. Each image represented a single frame in a larger story, essentially making the comic a video with an extremely low frame rate.-Taken from Wikipedia
