The artist Shinpei Takeda has created an art installation at the Hypocenter Park, Nagasaki. The installation comprises voice patterns (sound waves) from interviews with the survivors of the atomic bombing - hand drawn directly on the ground. The site has 13 hand drawn markers, which can also be downloaded for testing:

The app shows for each marker a pole with a title and an image using Augmented Reality (AR). When a marker is selected a short audio file of an interview in Japanese is selected for playing. The audio files can also be played manually. Additionally, in the AR visualization mode, the hand drawn patterns can be shown using AR at any place without marker.
