and now in 3D Print version (VIDEO).
The zoetrope consists of a cylinder with slits cut vertically in the sides. On the inner surface of the cylinder is a band with images from a set of sequenced pictures. As the cylinder spins, the user looks through the slits at the pictures across. The scanning of the slits keeps the pictures from simply blurring together, and the user sees a rapid succession of images, producing the illusion of motion.
In the case this 3D-printed Zoetrope which is called 3Drehkino (=3dturningcinema), a LED strobelight is triggered by each passing figure in its appropriate pose, flashing the strobe on it at the right time to give it the extremely realistic illusion of motion.
