It is well established that the spatial asymmetries of the overlap region in the initial state of a heavy ion collision, together with their fluctuations, are quite faithfully translated into final-state momentum anisotropies by a fluid-dynamical evolution. We investigate the relationship between initial-state eccentricities and final-state anisotropic flow harmonics for a simplified two-dimensional gas of massless particles. We show how geometrical fluctuations from a Monte Carlo Glauber picture are mapped onto flow fluctuations, in particular the dependence on the mean number of rescatterings per particle in the expanding system.
