May 11th, 2011 marks the 10th anniversary of the passing of Douglas Adams, English writer and dramatist, possibly best known for the series of books commonly referred to as the Hitchhiker's Guide to the Galaxy. The "trilogy in 5 parts" started life as a radio play and was reincarnated several times over the years in various print forms and on television before being released as a feature film in 2005.
As a gentle reminder of his amazingly quirky legacy, we've gathered images from the collection which refer to his work in some way, shape or form.
See how many references you can spot in our Thanks for all the fish lightbox.
"There is a theory which states that if ever anybody discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened." – Douglas Adams
So long, Doug. And thanks! We miss you!
