Books stream out a window like a burst of water from a giant hose. The sculptural installation, located at Casa de America, in Madrid, Spain, was created by artist Alicia Martin features 5,000 books cascading out of the building. The gravity-defying ''literary'' sculpture is eye catching due to its enormous size. So far, there have been 3 site-specific installations of massive sculptural works in the series called Biografias. Each one contains approx 5,000 books artfully stacked or scattered.
