We mark representations of the path algebra of a finite directed graph by a projective cover and consider the modules annihilated by the edge ideal. The resulting varieties are paved by fairly simple objects, and much of the geometry is carried by a 1-dimensional skeleton. （Joint work with Birge Huisgen-Zimmermann and Rekha Thomas）
