At the Turing Festival a few days ago I came across a guy from a company that had an iOS app inspired by Turing's secure speech communication machine, ">Delilah. Towards the end of WWII Turing worked on a device that could encrypt speech, transmit via telephone or radio and decrypt the speech. The device was not ready in time to be used during the war.
The guys at chirp.io have taken this idea and made an iOS app that can take a photo or note on your iPhone, convert it into sound and transmit it audibly to any iPhone nearby running chirp - no wifi, no Bluetooth, just sound
