“Butterfly Tree” is an Augmented reality application that allows you to view art works from a different view. When you run the “Butterfly Tree” application, the camera is automatically activated. If you look at the works installed in the exhibition space through the mobile camera, you can see the virtual graphic that was not seen when you saw the work with your eyes directly.
