We present a biased review of some of the most \’spectacular\’ effects appearing in the dynamics of granular gases where the dissipative nature of the collisions leads to a rich phenomenology, exhibiting striking differences with equilibrium gases. Among these differences, the focus here is on the illustrative examples of « Maxwell Demon\’\’-like experiment, modification of Fourier\’s law, non-equipartition of energy and non-Gaussianity of the velocity distributions. The presentation remains as non technical as possible.
