Spin angular momentum of a photon corresponds to a polarisation degree of freedom of lights. and such that various polarisation properties are coming from macroscopic manifestation of quantum-mechanical properties of lights. An orbital degree of freedom of lights is also manipulated to form a vortex of lights with orbital angular momentum. which is also quantised. https://www.spidertattooz.com/Fanimation-MAD8514-TriAire-52-Indoor-Outdoor-Ceiling-Fan/
