In this stop-motion video, I separate the space into two parts, right and left. The whole process is based on the rule that I add one piece of paper on the left first then add another corresponding piece on the right, and keep this process to the end. It is a black and white video, but it is still visible that two colors used in this work, which symbolizes two different decisions in each step. Based on this simple strategy, the final pattern come out from the independent steps. This short video aims to capture the idea that the intentional decision contributes to unintentional consequence by Adam Smith. I intend to find the relationship between individual and structure in this short video.
