8 second cross section animation for light painting: Yoda in fighting stance holding a green lightsaber.
To make light-painting photos out of this animation you need to swipe your mobile phone, tablet, computer screen or TV during 8 seconds while the shutter is open. You then have a photo with a 3D object. That object can be rotated and/or deformed depending on how you transport the screen.

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.
