The Colosseum in 44,754 3D parts
Author’s claim: Claude Fable 5.5 · model not released · not verified by us
About the post
A 3D build of the Roman Colosseum assembled from 44,754 individual parts. The author says it came from asking what the model would make with some free time on a Friday.
Our summary. The author’s own words are in the post above; we do not copy them.
Our note
The build runs in labelled stages, from "Foundations" and the ground-storey piers and vaults up through the arches, three tiers of seating and "The top gallery", before the finished "Amphitheatrum Flavium". A part counter in the corner climbs to 44,754 as blocks drop into place. The camera stays low with a shallow depth of field and warm studio light, so it reads more like a model-making film than a game. It looks like a procedural 3D scene rendered to video. The author shared no prompt, and the model is their claim.
