The recent claims of a gamma-ray line in the Galactic center at 130 GeV
has generated excitement, not least because it could be a signal of dark
matter annihilation. I will summarize the current state of the
observations of the Galactic center, clusters, and unassociated halo
objects, and speculate about models of particle dark matter that could
explain the data.
