In the famous discussion between Michael Weiss and John Baez about photons (at https://math.ucr.edu/home/baez/photon/schmoton.htm) it is suggested that photons are crowkscrews. See the image at https://math.ucr.edu/home/baez/photon/nicest.htm:
How can one use this this model of a photon to explain interference?

Any hint is welcome.
