Augmented reality application "Portable Museum" is an art project by Oleg Yushko which plays with the boundaries of the Visible and the Real, transforming the very concept of art in public space. The basic idea of this project is the creation of a smartphone-based AR museum. Such a museum should make it possible to exhibit and to view art directly in situ at any exhibition and in any public space regardless of given conditions. The application will create a whole new level of communication and interaction for artists and viewers.
