How this was made
“Create the most impressive thing I can share with people when you are introduced. It should grab them quickly. Be amazingly clever about it.”
That sentence went to Fable 5.2, Anthropic's new model. It chose the idea, worked out the orbital mechanics and wrote this page as a single file, with no images and no libraries.
Planet positions come from standard mean orbital elements and are good to within a degree or two. The Moon's phase is right to within about half a day. Heartbeats assume a resting 70 a minute, and star distances are rounded. The orbits are drawn evenly spaced, not to scale.
