Diary Book is a personal cartography of becoming — a dynamic photo-album shaped by sound, memory, and time. Through photographs from my birth to age thirty-three, the work traces my journey from a small town in southern China to France, from engineering and data science to a renewed artistic life. Paired with an original harp composition, these images breathe with quiet determination and awakening. Created in Max/MSP and JavaScript, the piece explores how memories transform into meaning and how an ordinary childhood unfolds into an extraordinary inner world.
