Abstract
A new kind of nonstationary hexagonal dissipative structure is found i n simulations of an optical-pattern-forming system. Since the brightne ss of the individual constituents creating the hexagonal lattice oscil lates with time, these structures may be named winking hexagons. They are formed by the resonant interaction of two hexagonal triads of spat ial modes. One of the triads is excited due to a Hopf bifurcation, the other one due to a static instability.
