Wind a watch, pull a machine apart, then take its explanation onto paper.

Anatomy, by Ryan (wheresryan22 on GitHub), guides coding agents to build interactive illustrations from code. Its October 18 update adds A4 and US Letter PDFs: a poster, a technical drawing and a longer illustrated handout.

These two original examples show the transition: a Raptor engine illustration running in the browser, followed by its printable poster. The shapes and animated effects are drawn by code. They are explanatory models; looking precise does not independently establish that every engineering detail is correct.

There is also a community gallery with other people's builds, including a typewriter, an Enigma machine and a medieval watermill manual.
