  The gluon field configurations that form the foundation of every lattice QCD
calculation contain a rich diversity of emergent nonperturbative structure.
Visualisations of these phenomena not only serve to explain the concept of a
nontrivial vacuum but also entertain a diverse audience from research funding
panels to the next generation of science enthusiasts. In this brief review, a
collection of QCD-vacuum visualisations is presented including the structure of
chromo-electromagnetic fields, centre-cluster evolution at finite temperature,
the structure of projected centre vortices, and novel correlations between the
electromagnetic fields of QED and the chromo-electromagnetic fields of QCD in
QED+QCD dynamical-fermion simulations from the QCDSF collaboration.
