My idea is to create a video piece that is triggered by a Carbon Monoxide Sensor. This video will be placed in smoking areas and in public places such as bus stops. Once a cigarette is lit the video will be triggered and start to play. A man will appear on screen and start to lecture the smoker on the effects on smoking. A webcam and other senors will be triggered to monitor the movements of the smoker. If the smoker tries to walk away the video the video will change and the lecture will start to shout at them.
