Nostalgia. It's delicate, but potent. Teddy told me that 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: around, and around, and back home again, to a place where we know we are loved.
