Literature versus Traffic by Spanish art collective Luzinterruptus.
An installation of 10,000 LED-lit books at Federation Square in Melbourne, Australia for The Light In Winter festival.
The books, recently retired from area public libraries, were given a second life as a glowing river that flowed through the square and into a nearby street. On the final day of the installation, onlookers were invited to take the books home.
This is so cool.
