Represents a utility-scale wind farm harvesting kinetic energy from moving air via horizontal-axis turbines. Rolling hills are generated with fractal Brownian motion (fbm) value-noise displacing a 140x140-segment plane, and 12 three-bladed turbines are placed with a minimum-distance scatter algorithm and spun each frame proportional to wind speed. Drifting cloud sprites cast matching soft shadow blobs on the ground to fake volumetric occlusion cheaply.
