The winning design, from a contest to create concepts for a premium but mass market mobile device capable of providing 4G or 5G multimedia service was made into a dummy handset for an exhibition in London's Air Gallery this week.

One of the designs, the Nokia Scentsory, is superb, partly because it reminds us of the paper clackers that we used to make many, many years ago in the innocent days of our childhood. In Closed mode you use it like a slim candy bar phone, in open mode you can use the screens and keyboard. But the real piece of resistance is the Scentsory mode that uses scent detectors that "allow you to see, hear, feel and smell your caller's environment".
