A semiconductor microcavity polariton fluid, injected by a nearly-resonant continuous wave pump laser can exhibit collective excitations which deeply modify its propagation. Superfluid behaviour of the polariton fluid is obtained and manifests itself as the suppression of scattering from defects. In other conditions Cerenkov-like patterns are observed. Microcavities polaritons are thus very good tools for exploring the physics of non-equilibrium quantum fluids.
