ORRERY SCRIBE: Gear-Driven Harmonograph

🎮 How to play

Drag to orbit, wheel / pinch to zoom; start the drawing, scrub the driver gear angle, change speed, X / Y eccentricity and curve preset, explode the assembly, export SVG / PNG.

A kinetic harmonograph: a 36:24 gear train and two Scotch-yoke frames move a pen over paper. Adjust the X and Y crank eccentricity, pick curve presets, scrub the gear angle, explode the assembly, and export the drawing as SVG or PNG. Idealised rigid-body model.
