There's a good chance you'll recognize a few of the clips featured in Welcome to Earth — a beautifully composed "universal time-lapse" made up of 179 of the internet's most stunning videos — but we're guessing you haven't seen them all, and you definitely haven't seen them like this.
At the bottom right hand corner of the video you'll notice each clip is labeled with a number. This number corresponds to a list (found here) where you'll find a link to the complete time-lapse from which the snippet is taken. There's some seriously great stuff here — including at least three videos that we've featured here on io9. (Clips 1, 16, and 112, for those who are curious.)
