We shed new light on local cohomology with support in an ideal defining a central linear subspace

arrangement.  We do so by making concrete relations between these local cohomology modules and the singular

homology of a family of simplicial complexes, which are related to the Hochster-Huneke graph of the associated

quotient ring.  This is work with Abraham Pascoe.
