This project is inspired from the memory of a childhood toy, gyroscope, which kids are fond of playing it. The interactions among kids prompt me to make this drawing device. It is also based on the movement and interaction between users. It reflects the result of the controllable and uncontrollable factors. Every time the gyroscopes generate different tracks. The tracks of ball and gyroscopes output some impressive patterns. The magnets on gyroscopes also add more uncertainty. Different kinds of balls, pens and pigments produce various kinds of paintings.
