A project that regularly sneaks noise into an optimized life by letting the chance to decide by chance or act in a way that is decided on the basis of one’s own intention and efficiency. Produce roulette. When you reach an intersection (such as a crossroad or Y-shaped road), turn the roulette and follow the path of the arrow that you pointed to. (The roulette is color-coded according to the number of branches. In the case of Y alley, look at the yellow part)
