This is pretty awesome to see since I did something related to this to simulate gravitational lensing around black holes back in 2000 under the guidance of Ronen Plesser at Duke University. Back then however, the computing resources I had available were far more primitive and I can't even imagine how long it would have taken me to render something like this back then. That said, this is way more advanced than what I was doing as well.
