  We report results on event-by-event hard probe of soft matter geometry and
fluctuations in heavy ion collisions. Geometric data ($v_2$ of high $p_t$
hadrons) from RHIC plus LHC clearly favors jet "monography" model with strong
near-Tc enhancement of jet-medium interaction strength which also implies a
less opaque medium at LHC. We also quantify the jet responses to all harmonic
anisotropy $v_n$($n=1,2,3,4,5,6$) and their manifestation in hard-soft
azimuthal correlations.
