Share secret messages in public places with this unique graphical code

PhonoPaper is a unique new way to graphically represent sound, including the human voice, so that you can leave secret messages in even the most obvious of public places. Created by Alexander Zolotov, the idea is based on a Russian synthesizer that was created during the mid-1900s. Available for both iOS and Android, the app brings old technology back to life in a way that it applies to the modern world.

PhonoPaper’s primary function is to convert sounds into images, which makes it easy for them to be re-read by the app. For those with an eye-for-detail, there is also the option to draw your message by hand, which not only allows for more experimentation, but a lot more mistakes in the process. One upside of PhonoPaper is that the code is analogue, which makes it almost immune to distortion caused by things like a poor resolution, lack of light, or wrinkled paper.
