Cardboard boxes can be a lot of fun for kids. With a little imagination and maybe some crayons and stickers, cardboard can become houses or spaceships or submarines. It may seem like technology is moving us away from finding joy in cardboard creations, but projects like Google’s Cardboard and Nintendo’s Labo are here to remind us that even where computers are involved, there’s still a lot you can do with everyday things — and there’s a lot we can learn from these efforts.
