The 120-cell can be partitioned into 12 disjoint 10-cell great circle rings, forming a discrete/quantized Hopf fibration.  Starting with one 10-cell ring, one can place another ring alongside it that spirals around the original ring one complete revolution in ten cells.  Five such 10-cell rings can be placed adjacent to the original 10-cell ring.  Although the outer rings "spiral" around the inner ring (and each other), they actually have no helical torsion.  They are all equivalent.  The spiraling is a result of the 3-sphere curvature.  The inner ring and the five outer rings now form a six ring, 60-cell solid torus. One can continue adding 10-cell rings adjacent to the previous ones, but it's more instructive to construct a second torus, disjoint from the one above, from the remaining 60 cells, that interlocks with the first.  The 120-cell, like the 3-sphere, is the union of these two (Clifford) tori.  If the center ring of the first torus is a meridian great circle as defined above, the center ring of the second torus is the equatorial great circle that is centered on the meridian circle.
