Cryptex Phone

Want to try out a phone that takes its design cues from an idea by Leonardo Da Vinci? Check out this nameless cryptex mobile phone concept. Designer Marc Schömann has certainly done well with this new cell phone concept known as the Cryptex phone.
This phone uses haptic technology to provide physical feedback for making a call. To turn it on…twist a section, to dial a number…twist a bunch of sections, to make an international call…break your wrist! There is no display and no buttons. The vibrate feature should prove popular with 50% of the world’s population.

You turn the dial of every element to the desired cipher. If you entered the number you turn the first segment “to phone” (green LED). If you want to hang up the call you turn the first segment to “hang up” (red LED). The phone works without buttons and without a display and based on the old dial phones.
