TITLE: Windwalker — A Kinetic Sculpture Simulation FILE: 093-strandbeest-walker.html === PROMPT (exact prompt used) === Create "Windwalker — A Kinetic Sculpture Simulation", inspired by Theo Jansen's wind-walking beach creatures (an original rendering). Simulate the Jansen linkage with its canonical link lengths (a=38, b=41.5, c=39.3, d=40.1, e=55.8, f=39.4, g=36.7, h=65.7, i=49, j=50, k=61.9, l=7.8, m=15), solving every joint position each frame from the crank angle with circle–circle intersections. Draw a multi-legged creature (e.g. 6–12 legs with phase offsets) walking across a beach (sand #e9d8b4, sea #6fb3c7, sky #f0f4f5) in its pale-yellow tube aesthetic (#f4e3a1 tubes with darker joints), with each foot's path traced as the characteristic curve and a wind sail driving it. Interaction: a wind slider (walking speed); a "single leg diagram" toggle showing one linkage with labelled lengths and its foot trajectory; a trace-paths toggle; buttons to add/remove leg pairs; drag to pan along the beach. Parallax clouds and footprints fading in the sand behind it. Typography: an engineering-notebook sans with monospace labels. SHARED REQUIREMENTS (apply to every page in this 100-page collection): 1. One standalone HTML5 file. All CSS inline in
