Today's Google Doodle celebrates Martin Luther King, Jr. Day, a holiday in the United States that remembers the famous leader of the African-American Civil Rights Movement.
The Doodle, which is featured on the homepage of Google.com, depicts Martin Luther King with several different faces integrated into the "Google" text of the logo. Around the drawing is a quote from King's most famous speech, his "I Have a Dream" speech. "I have a dream that my four little children will not be judged by their color of their skin … I have a dream today ... We shall overcome someday."
King's "I Have a Dream Speech" was 17 minutes long and presented on the steps of the Lincoln Memorial in Washington DC on August 28, 1963 to about 250,000 civil rights protestors.
