Build a kinetic sand table simulation. A ball must move through a bed of sand, leaving a visible trail, drawing complete geometric patterns, then smoothing the sand and starting a new and different pattern automatically. It must cycle through many different patterns without repeating. Everything about the look and the patterns is your choice.

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.
