I've been in Churchill for going on three weeks now and I've seen some incredible stuff and met some truly interesting people. Here's a couple of pieces I've done if you are interested.
The first is "Clash of the Polar Titans" which features some almost over-the-top music and polar bears sparring in the snow. Younger bears spar while they wait for the ice to come in just for something to do and to practice for when there's actually something to compete for. They have almost nothing to eat until they can get out on the ice.

And here's a somewhat less exciting compilation of three timelapses I did including one of the Aurora/Northern Lights.
