Like so many, I am loving Frozen Planet. While the shots of animals are just amazing (especially the whales), I was utterly entranced when watching the latest episode by a short but stunning sequence showing the spread of hoarfrost.
I couldn't resist creating some screen captures. I hardly watch tv these days, but the photography on this program takes my breath away.
Watch the latest episode, featuring the fantastic images above, on iplayer here (and you can even order a free poster of the polar regions!)
