The Pristitrope is a modification of the zoetrope, a pre-cinematic optical toy that shows short, looped animations. It replaces the zoetropes static illustrations with 18 tiny LCD screens, merging a digital way of showing images with an analogue way of showing their movement. The machine knows in which direction it is turning. Therefore, basic interactivity is possible, for example in the form of simple game structures or choices within a clockwise/counterclockwise narrative.
