In this talk I will introduce a class of Legendrian wavefronts associated to surface triangulations. First, I will explain the interplay between the Legendrian isotopy type and the combinatorics of the triangulation. In particular, we will be connecting symplectic geometry and graph theory. Then I will discuss the Floer theory of these wavefronts and provide a description of their dg-algebras. The talk will conclude with two geometric applications.
