Demonstration video: a time-lapse video of the Boston skyline

I created Reactor 1 in Fall 2010 as my final project for Interrogating the Digital Archive at RISD. Reactor is a Max/MSP program that generates an ambient soundtrack for a video feed in real time. The program responds to sunrise and sunset by changing the tone of the music: as the screen gets brighter, the music increases in pitch and moves faster. The program responds to sudden movement on the screen with flourishes of high-pitched notes.
