We've got vertigo watching this video, but in a good way! This is a sped-up view of Earth from the International Space Station from the Cupola, a wraparound window that is usually used for cargo ship berthings and Earth observations.
In the video you can see a solar array from the space station gliding by the view on the left, and Canadarm2 (the robotic arm used for dockings) just barely visible on the right side, near the end.
Behind the camera is the prolific video poster Reid Wiseman, an Expedition 40/41 NASA astronaut who has been quite active on social media. He's been posting pictures of the Earth on Twitter as well as numerous other Vine videos.
