At first, when you watch this video of perfectly pristine Antarctica, you can feel something off and even a little unsettling, but you don't know exactly what it is. It's not until you realise that the world has been mirrored in perfect visual symmetry that you see what's going on. The coolest thing is that only the landscape has been mirrored, the people and animals and boats in it have not.
So it's like everyone is living in a world where everything exists in perfect visual symmetry. Symmetry can be beautiful but living in it would be a nightmare. The video, Upon Reflection was made by Alex Cornell. You can see the gear he used for the video, here.
