“… in Greek, ‘nostalgia’ literally means ‘the pain from an old wound’. It’s a twinge, in your heart, far more powerful than memory alone. This device isn’t a spaceship; it’s a time machine. It goes backwards and forwards. It takes us to a place where we ache to go again. It’s not called The Wheel; it’s called The Carousel. It lets us travel the way a child travels. Round and round, and back home again, to a place where we know we were loved.”
