After playing around with Processing a bit I started investigating particle systems to simulate rope and cloth. I also started thinking up with other useful things that particle systems can do. In this sketch I utilize a streaming webcam to create particles. The sketch looks for changes in the webcam, indicating movement, and creates new particles at the location of these changes. Each new particle has an initial random velocity and is then subject to gravity. The particle's color reflects the underlying video stream. Eventually each new particle fades out.
