  We give an overview of recent developments in the theory of dimer models. The
viewpoint we take is inspired by mirror symmetry. After an introduction to the
combinatorics of dimer models, we will first look at dimers in dynamical
systems and statistical mechanics, which can be viewed as coming from the
A-model in mirror symmetry. Then we will discuss the role of dimers in the
theory of resolutions of singularities, which is inspired by the B-model. The C
stands for the connections that tie both subjects together: clusters,
categories, and stability conditions. In this final part we will give some
ideas on how these two stories fit in a broader framework.
