While digital books have been getting all of the attention lately, I have found a wonderful new book format being sold in a quaint bookstore in Milton Keynes - shredded books. The book is sent through an industrial shredder and voila - the book has been transferred into this new shredded format.
While this store sells the shredded books for list price, some art galleries have been selling them as "artist editions", fetching upwards of $1000 per book. The clerk disapproved of this practice and felt, in the end, it may kill this format from being embraced by the populace. And this would really be a shame.
Here is a picture of the copy of Gravity's Rainbow I purchased.
