Emergence

Performance becomes a visual biography

Visitors play a prepared piece on a MIDI keyboard. Rhythm, timing, and precision immediately influence the sound, color, pulse, and stability of a projected lifeline. Confident playing produces warmer and steadier motion; mistakes introduce colder colors, instability, and visible traces.

From lifeline to healthline

Each run moves through introduction, activation, development, climax, and reflection. At the end, the accumulated line condenses into a spiral-shaped healthline: a visual fingerprint of the performance.

TouchDesigner coordinates MIDI input, visual feedback, audio, timing modes, and a dual-projection setup across the screen and keyboard.
