To kick off their summer reading program, Seattle Public Library created a book domino chain. Here's the video:
Some people use stacks of books to hold up shelves
Others build reading nooks out of their books
And Brazilian artists Marcos Saboya and Gualter Pupo installed a maze of 250,000 books at the Southbank Centre in London. The maze forms the shape of writer Jorge Luis Borges' fingerprint.
What do you do with books when you're not reading them?
