風車・灯台・昼夜サイクル付きの浮遊ボクセル島

Build a small voxel world as a single self-contained web page, using Three.js, that the viewer can rotate around. Create a floating island with a rocky underside, a windmill with turning sails, a lighthouse whose beam sweeps at night, a village of red-roofed houses, a river that runs to the edge and drops as a waterfall, trees, flocks of birds circling and drifting clouds. Add a day and night cycle in which the sky darkens, windows glow and the lighthouse lights up. Use blocky voxel geometry with soft lighting, saturated greens and a pale blue sky by day, deep navy at night. Provide orbit controls with mouse drag and zoom, and a small title label. Everything should move on its own without input. Done means the island looks charming from every angle and the full day cycle plays smoothly.
