I highly recommend looking at the literature for really cool images with more complicated black holes.
Would be great if they coded this into Elite: Dangerous.
Now that Interstellar brought this image of a black hole into popular culture, I expect many other movies and games adopting it.

Interstellar? How about 'black hole'? http://www.imdb.com/title/tt0078869/
Performance thought: I like the way you raytrace the entire image at once. Clever, but you might be able to make it faster... Right now you process the entire image in one hit. However a 1080p * 4 byte image is 777,600 bytes - from a quick read I believe you have several of these. They're large enough to blow the caches in your CPU. It might be much faster to break the image into 8,16 or 32 square or rectangular or l…

Is it fair to compare this low-res photo to the render? I think they'll be prettier once we have better telescopes.
it's not about fairness, that's what we see currently.

Wow, I hadn't thought of that. I wonder what the "compression" factor is for each orbit around the black hole. Edit: Actually, I don't think you get any photons that do a full 360 degrees around the black hole that subsequently escape the black hole.
If you look at the image of geodesics he shows an example of an almost 360 degree trajectory. Simple continuity arguments allow you to conclude you can have an arbitrary number of rotations, I believe. I would conjecture the contraction is roughly exponential, there's no obvious contradiction with that but it's way over by knowledge to check it ...

By the time a photon has done a complete rotation, it necessarily has to be on a path that takes it into the black hole (instead of outside of it). So yes, you can have an arbitrary number of rotations, but anything that makes a complete rotation or more will never leave the black hole.
