StarCaster Zoetrope Spinner: Lit from within with a white LED this 3D printed spinner has pinhole tunnels precisely placed such that an animation of a swirling galaxy is created when spun into motion.

Borrowed a caliper stand for the fidget to allow a nice framing for video capture of the animation. A another curious creation by maker Mike of Prime Tower Designs. ➡️ Follow the link in
