The analysis of event-by-event fluctuations forms a central component of the study of heavy-ion collisions. It has been applied to a number of experimental observables, including anisotropic flow, mean p_T, and total charged multiplicity, and has yielded valuable insights into the evolution of the collision system. — In this presentation, I discuss some recent progress in treating the Hanbury Brown —Twiss (HBT) radii as fluctuating event-by-event observables and sketch how the properties of the resulting event-by-event HBT probability distributions could be accessed experimentally (http://arxiv.org/abs/arXiv:1512.07631 and http://arxiv.org/abs/arXiv:1512.07631).  I conclude by demonstrating how such experimental measurements are relevant to the Beam Energy Scan program and the search for the QCD critical point (http://arxiv.org/abs/arXiv:1702.01368).
