"Swiss engineer Jacques Piccard and Navy oceanographer Don Walsh descended to the bottom of the Mariana Trench, seven miles below the sea's surface. It's the lowest point on Earth, and deeper than any human had gone before - or since.
Above is a new video chronicling the explorers' journey, weaving animation with audio from an interview granted by Piccard in 2005, three years before his death. The interview was conducted by New York writer Victor Ozols, but went unpublished and eventually ended up on his blog. There it was found by German design student Roman Wolter, who made the film."

"Circles are sized by the number of medals that countries won in summer Olympic Games. Use the slider to view past Olympics, or click on a country to display a list of its medal winners."
(The New York Times)
[Interestingly although the map appears to have been created as a simple representation of the global medal tally the map also quite eloquently reveals aspects of the changing economic fortunes and political leanings of particular countries. Note for example Germany''s Olympic success prior to the Second World War and Eastern European success during the Cold War.]
