Carl Sagan's "Pale Blue Dot"

The Voyager spacecraft's "pale blue dot" photo, and Carl Sagan's audiobook commentary on it, have been the subject of literally hundreds of homage videos. The one I've embedded above is a bit grainy on the audio portion, but uses iconic clips from wonderful movies to illustrate the text. It's a 6-minute video; if you're in a hurry, begin at the 2-minute mark.
