Frozen Planet Trailer

This is Frozen Planet, which I was working for a while there..
Should be going out on BBC One soon (Oct?).
I was taking and interpreting data from NASA and commercial satellite scans and turning them into accurate, explanatory yet aesthetically pleasing globe views.
I was assisted in the task by the excellent Jessica Lee.
There is one at the front of this trailer there, but it has been compressed to **** on the YouTubes, there are at least another 6 million shades of snow in there on the full HD version.
(All the animals are real, btw.)
