This tutorial explores a method to ambiently light an area behind or surrounding a video display based on the colors and intensity in the video shown on that display. The included example uses four RGB lighting fixtures (or groups of RGB fixtures), which are controlled by color sampling each quadrant of the content being sent to the display. Also included in the download is a 3D model of the lighting setup so that you can view and fine-tune the effects without actual lighting fixtures. These effects are achieved by using QLab in conjunction with a program called Vuo.
