Not YouTube, but I have to share this:
Wanderers - a short film by Erik Wernquist
Quote:
“Wanderers is a vision of humanity's expansion into the Solar System, based on scientific ideas and concepts of what our future in space might look like, if it ever happens. The locations depicted in the film are digital recreations of actual places in the Solar System, built from real photos and map data where available.
Without any apparent story, other than what you may fill in by yourself, the idea of the film is primarily to show a glimpse of the fantastic and beautiful nature that surrounds us on our neighboring worlds - and above all, how it might appear to us if we were there.”
For what it's worth, vimeo is a place to go when you want to watch short films that aren't on the festival circuit.
