Reflective Kinetic Sculpture: this one translates rotating motion into repeating expanding (or shrinking) square-ish reflections. Directing two colored beams of light enhances the effect. An interesting one (of many) ways to connect rotational motion to translational motion. The base has a silent motor and connects to power via USB. ➡️ Follow the link in my profile for info on where to get this and other amazing items featured here on @physicsfun #windspinner #mathtoy #reflection #spiral #physic
