For the Poetry festival Cosmopoetica, Spanish artist Alicia Martin created a book cascade. The work is situated in Molino San Antonio covering a small, but a bit wild, stream of water. Martin used 5000 books to create this sculpture.
To see the work with sound of falling water, here is a small, touristic, clip of this sculpture: http://www.youtube.com/watch?v=E9Ey1nt-VgA&feature=related
