Cluster of white lights above Pittsburgh

My wife saw it first and pointed it out to me. Over the next few minutes we watched a strange formation of lights that changed shape (or formation?)... morphed several times. At first I thought it was a huge flock of geese (much bigger than any natural flock), but as if the "geese" emitted their own white light source. From our point of view on Mt. Washington looking directly north the formation came into line of sight right above the confluence of the rivers at the point of downtown. Approximate distance less than half a mile. It then meandered above downtown going to the right and then to the left and back again before continuing in an eastern direction and picking up speed dramatically. As it picked up speed it gained altitude and the lights flickered out of sight. As for shape it changed, but it did maintain a V of sorts. It resembled a cluster of stars.
