Lenovo brought concept laptops with 3D screens, foldable OLED, and solar panels to Mobile World Congress, along with new ideas for 3D gestures and AI accessories.

Lenovo has a history of showing off weird and interesting new product ideas at trade shows. Remember the laptop with the rollable display from a few years ago? This year at MWC it's doing the same thing, with a host of unique, fun, and downright silly ideas, some of which could inform designs and decisions for future products.
