In the last couple of years there has been much progress in constructing new exact vacuum black holes in five dimensions; but many of the resulting metrics are very complicated. In this talk I discuss the Pomeransky-Sen’kov doubly-spinning black ring, probably the most general connected black ring in 5D. I will show that it possesses an unexpected amount of hidden symmetry that allows the geodesic equation to be solved analytically in certain cases, with the resulting null geodesics having applications in constructing new coordinates systems that are valid across the event horizon.
