Here is a motion-model diagram of how stacked spins work and look, at the smallest level. We have an initial axial spin, then an X-spin outside the gyroscopic influence of the initial spin (caused by a collision with another photon), then the Y-spin, and then the Z-spin. This motion demonstrates that the photon as a discreet particle gains radius as the spins stack, and eventually becomes the electron, and later the proton or neutron, with additional stacking.
This is based on theory by Miles Mathis, and you can read more on the topic in his works. His paper, "How Do Photons Travel?" heavily influenced my interpretation, though I may not be fully fluent in his theory and may have a few mistakes left to fix. http://milesmathis.com/photon2.html
