Build a walking machine in the spirit of Theo Jansen's Strandbeest. Its legs must move through a real linkage mechanism driven by a rotating crank, so the walking motion is produced by the mechanism itself and not by hand-animated leg positions. It must visibly walk across the scene on its own. The number of legs, the environment, and the presentation are your call. Everything about the design is your decision: style, colors, mood, environment, camera, level of detail, and any extra touches. Do not ask me any questions, make every choice yourself and build the most impressive version you can in a single attempt. Technical requirements: one single self-contained HTML file, no external models, images, sounds, or asset URLs of any kind (a JavaScript library from a CDN is fine). It must start running on its own the moment it loads, with no clicks needed, and run smoothly with no console errors.
