Zoetropes are animation devices that gives the illusion of motion by spinning object or pictures while onlookers observe the device through slits, or in this case, a video. The device showcased in this video is the 4-Mation, a modular 3D zoetrope that features swappable animations. For those interested, the 4-Mation will soon be available for purchase via Kickstarter.
