Above left two are the works of Georgia Russell. She is a Scottish artist and works with "obsessive perserverance to create constructions that transform found ephemera, such as books, music scores, maps, newspapers, currency and photographs." ...Amazing... AndTakeshi Ishiguro's work (on the right) with Pop-Up Books. And I guess this Pop-Up Book really lights up when you open the book :)

And lastly, the pictures above are Robert The's art installation work with books.

...So many art forms just with books.
