Emergent Patterns in Video Feedback

My installation will be a video feedback system consisting of one camera directed towards an LCD monitor , focused in a way to produce geometric evolving patterns which morph over time. A second monitor (or video projector) provides an audience view of the feedback pattern without interference with the camera/monitor feedback system. Audience members are encouraged to interact with the feedback system using various physical objects introduced between the camera and monitor to change the variables in the light feedback loop.
