@airobotcat: AI Animation Battle: DNA Double Helix 🧬 Which AI did it best? Prompt: Create a single-file HTML page using HTML/CSS/vanilla JavaScript only (no external assets). Render a centered square scene container with a thin white border around the frame. Inside the frame, simulate a rotating DNA double helix structure made of two twisting strands connected by base pairs. The helix should slowly rotate while subtle particles float around it. Use a rather dark background inside the frame to highlight the glowing DNA strands. Motion must be smooth and continuous for 30 seconds, then reset seamlessly. Add a Start button below the square that starts the animation when clicked.
