A black hole renderer written from scratch in Python

Asked for the hardest edit it could make, Claude Fable 5.5 traced every pixel as a light ray bent by the real equation for a non-rotating black hole. No game engine, stock footage or textures: Python on 2 CPU cores, in about an hour.

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.
