- Worth noticing
- The catalog stays in Brown’s original order; a status ledger identifies which mechanisms run and which still link to his text and figures.
Field notes
The method section says models are tested in Python and run in the browser through WebAssembly, with MuJoCo handling the physics. Belts are described as elastic-link chains held by tension and friction, while gears rely on colliding involute teeth. Brown’s text and figures are identified as public domain, and the page credits scans to 507movements.com.
