Rainfall vs ParticleFluid

Open Rainfall and you're looking down at a dark, still pond at night — and it's raining. Every drop falls with real depth: far rain drifts soft and slow, near rain streaks fast and bright. Where each drop lands, a ripple opens and spreads across the water. Let them overlap and the ripples interfere, weaving a living lacework of light. This isn't a loop of stock footage — it's a living scene you can touch. Reach in and stir the water Tap anywhere to send rings blooming from your fingertip, each with a soft splash. Drag across the surface and ripples trail behind your finger. The rain is yours to play with. Tilt the sky Lean your phone and the rain leans with you, slanting on the wind. Give it a shake and a gust sweeps through, then settles. It feels alive in your hand. Thunder in the distance Now and then the sky flashes, and a beat later thunder rolls in — never the same twice. Close your eyes and you're far from everything. Make it your rain Choose a mood — Night Rain, Ivory, or Molten Gold — or set your own colors for the rain, ripples, and sky.

ParticleFluid is an interactive 2D fluid simulation that lets you swipe across the screen to apply force to a velocity field and watch particles flow in real time. Adjust the particle count, swipe sensitivity, and viscosity to explore fluid-like motion. Its minimal interface keeps the focus on the particles and their movement.
