Our eye retains an image for a fraction of a second after seeing it. When the top spins, the offset blades of the spiral move faster than our brain can follow: the images overlap, and we perceive a movement that does not exist, a wave that seems to rise or dive towards the center. It is the same principle as the spiral discs of old optical toys.\u003c\/p\u003e\n\n\u003cp\u003eThe shape itself is only possible thanks to \u003cstrong\u003e3D printing\u003c\/strong\u003e.
