Giant Dust Clouds DO Move

You really get a sense for the magnitude of these vast interstellar dust clouds as you watch them move in a few of these animated gifs. Then you realize truly how big they are after seeing the dates indicate that they move this far only after a decade! Amazing how intuitive their movement is, even on such an impressive scale!
