Thanks to Eric, whose gmail status message turned me on to Pale Blue Dot, a film by George Fu. Go watch it. It's that good. You'll need to download a DivX video player plugin for your brower, which is somewhat irksome if you're on a low bandwidth connection, but worth it for those blessed with broadband.
The short is less than six minutes long, but that's more than long enough to deliver a a moving narration from Carl Sagan that puts humanity and our small planet in the kind of perspective that perhaps only an astronomer can.
When that narrative mashed up over a montage of dozens of the most iconic moments from the history of film and popular culture, c'est voila:
Transcendence. Or something approaching it.
