Abstract We investigate the patterns formed by thin liquid films evaporating from clean substrates. The system in equilibrium is entirely homogeneous, yet a remarkably regular, symmetric pattern is generated by a change in an isotropic parameter: the vapor pressure. The hydrodynamic instabilities which come into play display strong nonlinearities, distinguishing them from the classical capillary instabilities described by Rayleigh.
