This app uses the device’s light sensor to display a picture and a song that tell you to turn the lights off when the room lights are on. When you switch off the lights, the light sensor detects this action and a funny picture that says “Who switch off the light?” is displayed. If you switch on the lights, the first picture is displayed again.
