We don't have labels on the walls at Mona. We have the O. The O uses location awareness to locate you in and around the museum. Use it to find out about artworks nearby, food and drink options, music performances, and other stuff. Love or hate what you see, join virtual queues and wander off, save your visit, and read and listen in your language. Think of the O as your own personal visitor guide at Mona. The O is also how you navigate the Phrontisterion, Mona's library. It replaces Dewey — charting a course through the collection and linking books by association, theme, or obscure whim. Point the camera at any book cover and reveal myriad connections to other items. Search by title, subject, or curiosity. Follow a thread from one book to another, and then somewhere you didn't expect to end up. The O knows where everything is and will take you there.
