An extension of a black-hole effect simulation with procedural, emissive clouds. CCs welcome.
The Black Hole Material in the relevant .blend files is from a file I got from blendswap, and I promise I'm trying my best to find the source URL and I will update this as soon as I can.
If you know who it might be, hmu.
If this is you, most def hmu, collab?
It's basically a mesh based hack to pretend to curve light. Think how dominoes would be arranged if you were making a half turn about 6 inches wide except it went down the surface of the sphere. So it's basically more of an acorn shape. And its glass with a variable IOR along the inner axis.
Simple procedural clouds texture with emissive properties and volumetric absorption.
