Sometimes icebergs flip over. It's apparently a fairly rare occurrence, but when it happens it exposes something alien and mesmerizing. As he sailed through the Drake Passage to Antarctica, Interface designer Alex Cornell caught the appearance on his Canon 5D Mark II camera.

“We were lucky to see a massive iceberg flip; when this happens, the color is a surreal, alien blue. They don’t flip often, so it was a pretty rare sight to see. It’s hard to tell scale, but this was an epic iceberg. It was amazing to see the interior. There were air bubbles and flowing water throughout. It looked like an alien artifact.”
