Swimming inside an iceberg looks amazing because the ice looks like glass and that's crazy, and because it kind of resembles an underwater version of Superman's Fortress of Solitude. Or at least, like a crystal palace. National Geographic shows us how a free diver explores the ice cold waters below.
We all want to be Superman, but sadly can't be—so maybe the nearest we can get is building his pad out of Lego. At least that's what Chris Melby thought when he constructed this sensational model of the Fortress of Solitude from scratch.
Here's the secret door to Superman's Fortress of Solitude. Or its toilet pipe. Or just an awesome photo of an ice column in a tunnel carved in the rock, near Lake Tahoe. In any case, a beautiful image. [Full Frame Collective—Thanks Attila Nagy!]
