  We develop a lattice gas model for the nonequilibrium dynamics of
microemulsions. Our model is based on the immiscible lattice gas of Rothman and
Keller, which we reformulate using a microscopic, particulate description so as
to permit generalisation to more complicated interactions, and on the
prescription of Chan and Liang for introducing such interparticle interactions
into lattice gas dynamics. We present the results of simulations to demonstrate
that our model exhibits the correct phenomenology, and we contrast it with both
equilibrium lattice models of microemulsions, and to other lattice gas models.
