Libraries tend to house their stacks indoors, which makes FLUX's art project Lacuna something of a first: a series of nook-friendly triangular wooden shelves, lightly canopied by pages suspended on wires, Lacuna was designed specifically for this year's Bay Area Book Festival. Better yet: the project had no late fees. The intent of the project was to encourage people to permanently take away 50,000 books donated by the Internet Archive while simultaneously creating a space conducive to reading. According to the Mercury News, FLUX art director Benjamin Anderson saw the project not only as a means of pumping out the volumes, but also of creating greater aesthetic engagement within the public realm. "We as a society often see art as strictly hands-off," he explained. "It's OK to look, but not touch. One of the benefits of doing big art is that we get an opportunity to push that innate hesitation."

FLUX is no stranger to specific behavior-inducing structures, having previously designed installations for Coachella, among other places. Fittingly, the term "lacuna" refers to a missing portion in a book or manuscript, as well as an unfilled space or interval. The installation, which purposefully integrated both semi-secluded shelved spaces and wide open stretches around a central fountain, could be said to have been sited at the intersection of literature and architecture.
