  When a simple or complex liquid recedes from a smooth solid substrate it
often leaves a homogeneous or structured deposit behind. In the case of a
receding non-volatile pure liquid the deposit might be a liquid film or an
arrangement of droplets depending on the receding speed of the meniscus and the
wetting properties of the system. For complex liquids with volatile components
as, e.g., polymer solutions and particle or surfactant suspensions, the deposit
might be a homogeneous or structured layer of solute - with structures ranging
from line patterns that can be orthogonal or parallel to the receding contact
line via hexagonal or square arrangements of drops to complicated hierarchical
structures. We review a number of recent experiments and modelling approaches
with a particular focus on mesoscopic hydrodynamic long-wave models. The
conclusion highlights open question and speculates about future developments.
