Students look at audience-responsive work such as Rafael Lozano-Hemmer's Body Movies and Daniel Rozin's mechanical mirrors, and discuss what it means for a viewer to complete a work. The teacher provides a p5.js starter sketch that measures two things only: how much the webcam image changes between frames, and the microphone volume, with no face detection and nothing saved or sent anywhere. Over five lessons each student designs how these two inputs drive their piece, for example stillness letting a field of particles settle into a form and sudden movement scattering it. At the class exhibition spectators choose whether to take part, a sign explains what the piece measures, and anyone who prefers not to be on camera can use the mouse instead; each student presents with a 200-word artist's statement.
