In early 2010, the Stedelijk Museum partnered up with design agency Fabrique and augmented reality firm Layar to develop virtual art tours called "ARtours". Using smartphone technology, visitors are treated to additional stories and images about the collection both inside the museum and outside around the city. In the final phase of this project at the end of 2011, the public was invited to add their own stories, images, and other information through the open source platform.[26]
