On November 8, 2013, on Google's home pages, is a special logo for the 129th birthday of Hermann Rorschach. Hermann Rorschach is most well known for developing the inkblot test.
The interactive Google Doodle, which you can see now on Google Australia (where it is the 8th already) shows various inkblots and asks you to share what you see on Google+, Facebook or Twitter.
Here is a video of the Doodle:
Hermann Rorschach was born on November 8, 1884 in Zürich, Switzerland and died at the young age of 37 on April 1, 1922 in Herisau, Switzerland. He was a Swiss Freudian psychiatrist and psychoanalyst best known for his inkblot test for projecting your thoughts.
