Pulse is a sound-interactive piece. The computer’s built-in microphone detects sound and allows Processing to draw images according to the music. There are two songs used in this piece, composed by myself. The first song is a piano piece. When it’s played, Processing draws soft, ripple-like images that viewer can control with arrow keys. The second song is a dance piece made with Garageband. Viewers can control the visuals by moving and clicking mouse.
