Augmented reality...
Some time ago I was in a Lego store with my Grandson. I noticed a Monitor across the store with instructions. I encouraged him to pick up a kit , and walk over to the screen. We could see him holding the box and a 3D animated view of the completed kit. He could turn the box around to view from different angles. How I envy the next generation and how the world is changing with AR and many other ways.
