Those who love art know it: it is difficult to find the words to explain the emotions you feel when you are standing in front of a sculpture by Canova, Donatello or Bernini. Equally complex it is to describe how incredible it may be the experience of admiring the Pietà by Michelangelo, turn around it, rotate it with your own hands, make it smaller and move it on a desk. The tool that make this possible is Microsoft HoloLens, the first stand-alone holographic computer that allows people to get in touch with digital content, interact with holograms and to obtain the access key for Mixed Reality.
