Hundreds of fireflies drift and blink over a swaying, wind-blown meadow lit only by moonlight. Each firefly is a glowing point sprite whose brightness pulses on a sine-based flicker curve, while a handful of them also drive real point lights that cast soft green-gold glows onto the grass below. The grass itself is thousands of instanced blades that gently sway using time-based rotation offsets.
