Arduino, servo motor, very strong LED light and PING ultrasonic sensor. Programmed in Pure data.
How it works: Screen on the TV remains blank until ultrasonic sensor which is placed on the front side of the box gets the information of object (person) on a distance smaller than 2 meters. Distance corresponds to a scale that gradually switches on/off the light (and sounds) and therefore makes the image on screen visible – as you approach the TV, shadow of moving Charlie Chaplin figure becomes stronger and stronger, and vice versa, and the loudness of sounds/ music increases as well.
