  Bipartite graphs, especially drawn on Riemann surfaces, have of late assumed
an active role in theoretical physics, ranging from MHV scattering amplitudes
to brane tilings, from dimer models and topological strings to toric AdS/CFT,
from matrix models to dessins d'enfants in gauge theory. Here, we take a brief
and casual promenade in the realm of brane tilings, quiver SUSY gauge theories
and dessins, serving as a rapid introduction to the reader.
