The original McKay correspondence compares graphs arising from the representation theory and the geometry of a finite subgroup of SL(2,C). I will discuss joint work with Alastair Craw and Rekha Thomas where we consider the case of an abelian subgroup of GL(n,C). In this case much can be reduced to combinatorics of polytopes.
