i believe that what we perceive and conceptualise as matter, do indeed have an internal jitter, in internal teeming motion. only when the conceptualisation is too rigid, like in the case of 'point particles model', it seems inadequate.
particles do not exist. it is just a model that we apply on a certain scale. however, that which we project our model of nonexistent particles onto, does spin, if we change our model from static idea of atom or particle, or a given something, to a spherical standing wave. the whole of space teems, jitters. so every 'point' performs spherical rotation - spin.
matter is just undulation in the fabric of space.
if Dirac was right then what we call particles do spin. their axies are object-centered, with just a point of their intersection that stays invariant.
this is one of best info on spin i read ever:
from page 3634 on, in tony smith's webBook. google "tony smith physics", you find tony's home, down at the end of the page is his whole website as a pdf file. it has 100mb, but it's well worth it.

btw, houserichichi, did you already skim through his ideas (you said you plan to do so)
