SE veterans will probably be unimpressed by the shader itself, but for a while now I've been working on a black hole and wormhole shader inspired by SE's for the Unity engine, and it just got approved on the Unity Asset Store!

(For those worried: I did not just decompile and resell SE's shader. I used it as a visual reference, but mine was written from the ground up, functions rather differently, making use of different mathematics, and is more heavily optimized for performance and cross-platform compatibility.)
