Seems like Vimeo is really serving up good stuff now. Erik Wernquist[a] has created a jaw-dropping short film of his vision of humanity's expansion throughout the solar system.
As Phil Plait over at Bad Astronomy[b] put it:
[T]ake a moment and let this sink in: Nearly every location depicted in this video is real. These aren’t just fanciful places made up in the head of a special-effects artist; those are worlds in our solar system that actually exist. And many were based on images taken through telescopes, or probes that have physically visited these distant locales.
...
Nothing in there is impossible; no faster than light travel, no wormholes. Even the space elevator shown towering over Mars and the huge cylindrical rotating colony in space (did you notice the Red Sea in it?) are problems in engineering, not physics. We can build them.
For now, though, I'll have to make do with Kerbal Space Program.
