A rain-slicked back alley bathed in the glow of hand-painted neon signage, evoking the dense, moody atmosphere of cyberpunk cityscapes. Wet asphalt acts as an imperfect mirror, showing faded reflections of the signs above, which is how light behaves on rain-soaked pavement in real cities at night. Thousands of individually simulated raindrops fall at slightly different speeds through volumetric fog, scattering the colored light from the signs the way real rain droplets refract and diffuse point-source illumination. Each sign flickers on its own cycle with an occasional random dropout, mimicking the imperfect ballast and aging tubes of real neon and LED signage. Use the controls to speed up or slow down the rain, adjust sign brightness, thicken or thin the fog, and toggle auto-rotation of the camera.
