  This presentation examines the centre vortex structure of Monte-Carlo
generated gauge-field configurations using modern visualisation techniques.
This time, the manner in which light dynamical fermion degrees of freedom
impact the centre-vortex structure is explored. Focusing on the thin vortices
identified by plaquettes having a non-trivial centre phase, the vortex
structure is illustrated through 3D renderings of oriented plaquettes. The
impact of light dynamical fermions is not subtle, changing both the density of
vortices and the complexity of the vortex structures observed. The role of
vortex branching points in full QCD is highlighted in the survey of results
presented.
