This outdoor interactive work pairs a robotic arm with the Moon to create light-painting photographs. Participants speak a secret into a microphone; their voices become waveforms and robotic movements, captured through long exposure with the Moon as the sole light source.

However precisely the robot depicts the waveform, the final image remains subject to air quality, cloud density and lunar phase. When the Moon is visible, the secret appears in cryptic form; when it is hidden, the secret dissolves into the night sky. Either way, it remains a secret—translated into another language.
