This is extremely cool; it's the best explanation I've come across yet of the Interstallar visualisation. And yet frustrating - I have dangling questions. Why does the ISCO have a fuzzy inner edge? What is the fuzzy semicircle of light that appears below the accretion disk, outside the photon sphere, but inside the ISCO, in only the lower half of the image? I get less than half a second of motion for these images, and I can't make them restart. It would be super-cool to get motion video that ran continuously, or at least in a loop.

It's possible to see the acceleration disk behind the black hole from both sides. Above arch is the upside, below is the downside. That's the outermost disk. It's also possible to see the up- and downside of the front part of the acceleration disk from both sides second time from the light that circulates the black hole. I think the fuzzy part that joins photon sphere is the light from the upper part of the front of the acceleration disk. Going once around the black hole. When you go you go off axis (upwards) the lower side becomes fussizer/wider and other side mixes with the photon sphere.
