Google has a special set of 16 logos for the late Roger Hargreaves's 76th birthday. Roger Hargreaves was born May 9, 1935 in Cleckheaton, Yorkshire, England, UK he died at the age of 53 on September 11, 1988 in Royal Tunbridge Wells, Kent, UK.
He is most well known for his work on the Mr. Men children books. Because of those works, Google has decided to remember his life today with a series of 16 logos. The logos are randomly loading on refresh on the Google home page. I believe the logo can be found on all Google properties (US, UK, India, etc).
I've put together an animated GIF of the logo that switches between the 16 logos every second. You can see the animated GIF version above.
Here they are by name, individually:

Little Miss Sunshine:
Little Miss Chatterbox:
Mr Uppity & Little Miss Na:
