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.

The Lenovo ThinkBook "Codename Flip" concept runs with the idea of versatile 2-in-1 laptops. It raises it to new heights (quite literally), fitting a vertically massive 18.1-inch foldable OLED display into a sleek 13-inch notebook.

Lenovo is showing off its most outlandish concept designs at Mobile World Congress, including an OLED screen that folds backwards and a triple-monitor laptop expansion.
