Snow Swarm
Snow Swarm is a mobile, touch-only interactive toy where you become the light. Drag your lantern-cursor across a warm nocturnal scene and thousands of moths respond with real phototaxis—orbiting, spiraling, and resting on the glow. Draw light-paths to choreograph the swarm into flowing shapes, then long-press to flare and scatter-bloom the whole cloud in a breathtaking burst. Moth wings catch the light individually while swarm density forms soft, living body shapes. When you finish, the app composes a swarm-choreography long-exposure card you can share to the community or replay. Built portrait-first with safe-area handling, an EN/中文 language toggle, and no external services, logins, or music.
