Everyone loves a good snapshot from space, so astronauts at the International Space Station regularly serve them up for NASA-lovers on Earth. Now one space traveler is working on something even better.

This weekend, astronaut Ron Garan tweeted that he was working on a time-lapse photography project and then released a "preview" of the results. That video is embedded above. Maybe it's not as worldchanging as the original Whole Earth photo, but it's dynamic and gorgeous.
