Our note
A three-minute 3D history explainer that moves from uranium fission in Berlin through Chicago Pile-1 and a map of US sites to the Trinity test; the creator says it wrote its own renderer and soundtrack across 5,400 frames.
The creator’s post
Asked Claude fable 5.5 for a 3-minute 3D film on how the atomic bomb became possible. It had no 3D library to work with, so it wrote its own renderer, drew 5,400 frames, synthesized a soundtrack and sent me an MP4.
