  Angular correlations of two and more particles are a sensitive probe of the
initial state and the transport properties of the system produced in heavy-ion
collisions. Two recent results of the ALICE collaboration are presented.
Event-shape engineering, a novel method, is applied to Pb-Pb collisions which
splits events within the same centrality interval into classes with different
average flow. The results indicate an interplay between radial and elliptic
flow likely related to the initial-state eccentricity. In pp and p-Pb
collisions, recent results revealed intriguing long-range correlation
structures reminiscent of features observed in heavy-ion collisions. The use of
forward detectors allowed to show that long-range correlation structures
persist also at large rapidities in p-Pb collisions.
