To flick the lights, swipe your hand downwards through the air. It's a bit laggy so make sure you wait until the video appears before flicking the switch. Also, make sure your computer doesn't move and there isn't any background movement as it is quite sensitive. Sometimes, the lights will go off before the video starts because it starts sensing you before the video comes on. Remember to not swipe too fast. Type 'yes' to turn the lights on again (without capitals). Typing anything else will end the script. Have fun!
It's a bit buggy at the moment
