Nintendo’s big new surprise interactive experience for the Switch is now official, and it’s basically a maker kit for the portable console that uses cardboard component pieces to allow people to build a range of different creations and play with them using the console to power games that interact with the DIY components.

NintendoLabo is like a next-level LEGO, with kits that let you do things like build working pianos that interact directly with Switch software, and even make your own robots. Nintendo shows off an interactive fishing game with a real, build-it-yourself cardboard fishing rod you can use to catch stuff in-game, and a rolling bot you can remote-control with the Switch’s touchscreen, as just a couple of examples.
