This has to be the coolest interactive map I’ve seen in a long time, and timely.  It’s a clever geographic representation of the Olympic medal count (at the bottom of the page you can see the more conventional medal count in table form).  The more medals your country has, the larger it’s depicted on the map.  The best part, though, is that this map does as much for every Olympics back to 1896.  It’s rich to see which countries were dominant in which years.  The first Olympics was a surprise.  Then see the U.S. emerge as a world power in the early 20th century.  See England’s former glory.  See Germany in 1936.  See the Communist Bloc in the 1980s.  Great informational delivery.
