Wow: the xkcd webcomic had
an entry called "Time" a while back that was notable because the image updated every hour(?), gradually telling some sort of story. Some dedicated people have been following it carefully, and it just reached "The End" in the past day or so (3099 frames total!). The story starts out pretty slow, but it builds to a strong conclusion, and it's awesome.
Here's
a site where you can let all of the frames play back automatically at high speed (with brief pauses for frames with dialog or noteworthy events). It's worth watching!
Incidentally, there's clearly a lot of backstory that is never fully revealed along the way. Evidently there's
a whole community trying to piece some of it together. Just as one thing to watch for, near the end you'll get to see two maps. Pay attention to the second one (and maybe tilt your head a little). Evidently even the details of the stars are important.
