In recent years, lattice fluids -- collections of discrete
particles constrained to move about on a lattice according to
simple deterministic interaction rules -- have been used to study
fluid dynamics.

These models are of nanotechnological interest for at least two
different reasons: First, they have proven to be a
computationally efficient alternative to molecular dynamics for
studying mesoscale dynamical phenomena in complex fluids such as
microemulsions, which have been proposed as means of
nanofabrication.  Second, such reversible "cellular automata"
models are themselves amenable to extremely fast implementation
on special-purpose computer hardware -- both existing and
envisioned.

There is thus every reason to believe that such discrete
algorithms will play an important role in the future of
computational physics.  This talk will survey the development of
lattice fluid models and especially their application to complex
fluid dynamics, offer comparisons to continuum models and to
molecular dynamics, and speculate about the future of this
rapidly developing field of study.
