Designer Wan Fu Chun has come up with a very convenient and ergonomic idea – a keyboard that can be customized by its user. Dubbed Puzzle, the keyboard allows users to arrange keys in whatever way they see fit. This means that keys can be left out, put in alphabetical order, or even turned into a different shape. We recommend buying one of these for somebody you like to play pranks on. ‘Good luck writing words without vowels… sucker’.
