Here in Copenhagen at the COP-15 Climate Change Conference, a giant art installation called "The Cube", is playing YouTube videos submitted on youtube.com/cop15 all day long. It's part of our climate change campaign with CNN, in which YouTubers can submit videos for our CNN/YouTube town hall.
The cube represents a cubic ton of carbon, and is located on a small pond near the planetarium in Copenhagen. Since it's dark for much of the day in Copenhagen, the visual display is quite stunning.
Find out more about The Cube in the video description of this clip:
