Google Doodle pays tribute to The Hitchhiker's Guide to the Galaxy author

Today’s Google Doodle pays tribute to the author of the comic science fiction phenomenon that is The Hitchhiker’s Guide to the Galaxy.
Created by Douglas Adams, born today in 1952, Hitchhiker’s Guide to the Galaxy is a comic science fiction series that was originally broadcast on BBC Radio 4 in 1978.  Later, it developed into a “trilogy” of five books that sold 15 million copies in Adams’s lifetime.
In 2005, a Hollywood film version was released starring The Hobbit: An Unexpected Journey’s leading man Martin Freeman.
The doodle lets users play with several interactive illustrations, the concepts of which feature in the book itself.
Adams died of a Heart Attack in 2001.
