  The recent measurements of the global polarization and vector meson spin
alignment along the system orbital momentum in heavy ion collisions are briefly
reviewed. A possible connection between the global polarization and the chiral
anomalous effects is discussed along with possible experimental checks. Future
directions, in particular those aimed on the detailed mapping of the vorticity
fields, are outlined. The Blast Wave model is used for an estimate of the
anisotropic flow effect on the vorticity component along the beam direction. We
also point to a possibility of a circular pattern in the vorticity field in
asymmetric, e.g. Cu+Au, central collisions.
