Google's home page today has a very entertaining dance logo to commemorate the 102nd birthday of Frankie Manning. Frankie Manning was a dancer who was one of the founders of the dance style Lindy Hop.
Lindy Hop was a American dance that evolved in Harlem, New York City, in the 1920s and 1930s and originally evolved with the jazz music of that time. You basically swung your dance partner around a lot in a very fun and fast paced dance routine.
Clearly, the logo is depicting that.
Frankie Manning was born on May 26, 1914 in Jacksonville, Florida and died on April 27, 2009 at the age of 94 in Manhattan, New York City. Manning was inducted into the National Museum of Dance's Mr. & Mrs. Cornelius Vanderbilt Whitney Hall of Fame in 2009.
