  Given a finite graph G and a topological space Z, the graphical configuration
space Conf(G, Z) is the space of functions V(G) -> Z so that adjacent vertices
map to distinct points. We provide a homotopy decomposition of Conf(G, X x Y)
in terms of the graphical configuration spaces in X and Y individually. By way
of application, we prove a stabilization result for homology of configuration
space in X x C^p as p goes to infinity. We also compute the homology of
Conf(K_3,T)/T, the space of ordered triples of distinct points in a torus T of
rank r, where configurations are considered up to translation. In Section 2, we
give an algorithm for computing homology of configuration space in a product of
simplicial complexes. The method is applied to products of some sans-serif
capital letters in Example 2.12.
