Nintendo unveiled what it calls a “new interactive experience” for Nintendo Switch today that’s unlike anything else on the console. Called Nintendo Labo, it’s a “new line of interactive build-and-play experiences that combine DIY creations with the magic of Nintendo Switch,” according to Nintendo.

Labo will let Nintendo Switch owners build cardboard versions of real-world items like a 13-key piano, fishing rod or motorbike. Nintendo calls those cardboard creations Toy-Cons. And, by inserting Joy-Con controllers into those Toy-Cons, players will be able to play games themed to the cardboard creations.
