To make light-painting photos out of these animations you need to swipe your mobile phone, tablet, computer screen, TV during 10 seconds (or more if you intend on drawing more objects) while the shutter of your camera is open. You then have a photo with a 3D object that can be rotated depending on the direction you transport it. The best way to "swipe" manually is to imagine your device is a CT scanner and you're essentially assembling an imaginary object with light. Each object has a different length which means some animations are to be swiped over a shorter distance than others. The size of the screen also obviously affects the distance it has to travel.
