When i was a kid, we used to dream about the "ping-pong" machine of light. Basically- the light bending of the black holes allowed for images of the sky to be stored, distorted and bounced around to almost noise - of skys objects in diffrent times.. Drive it through a simulation, and you could see a nova light up, reflected back from the ping-pong machine over the aeons.. There was this nasa book, "Cycles of fire" we sat and daydreamed about..
