Now this Cryptex phone concept is definitely interesting, although I wouldn’t rely on it when I have to dial a number in an emergency. After all, you will need to twist each individual number before a call can be made, making it extremely cool but not user friendly at all. Haptic technology is used for physical feedback whenever you make a call. Designed by March Schomann, the Cryptex phone concept also comes with a vibrate feature that ought to appeal to at least half of the world’s population.
