Abstract: Let $ K$ be a finite simplicial complex and $ f:K \to K$ be a "skeletal" map. A digraph $ D$ is defined whose vertices correspond to the simplexes of $ K$ and whose arcs give information about the behavior of $ f$ on the simplexes. For every walk in $ D$ there exists a point of $ K$ whose iterates under $ f$ mimic the walk. Periodic walks are mimicked by a periodic point. Digraphs with uncountably many infinite walks are characterized; the corresponding maps $ f$ exhibit complicated behavior.
