Our note
A black hole renderer Fable 5.5 wrote from scratch in Python: every pixel is a light ray bent by the Schwarzschild metric, with no engine, stock footage or textures, rendered on two CPU cores in about an hour as the camera orbits the disk.
The creator’s post
I asked Claude fable 5.5 for the hardest edit it could make. It wrote a black hole renderer from scratch. Every pixel is a light ray bent by the real equation for a non-rotating black hole. No game engine, no stock footage, no downloaded textures. Python, 2 CPU cores, about an hour.
