Everything from Dilbert to Pac-Man has shown up in Google's legendary doodles. Here are a few of the most notable throughout the years.
Instant search - September 8, 2010
This doodle is animated, but not interactive. Google presented this doodle, which 'types' the Google logo out (well, converts it from white to colourful), on the same day that it introduced its new Google Instant search feature. Under Instant search, with each letter you type in your query, Google spits back evolving results.
Imagine - October 8, 2010
This doodle appeared on what would have been John Lennon's 70th birthday. Instead of an e, Google's logo sported a play button. Clicking the button brought up a short, animated video set to Lennon's 'Imagine'.
