## What is Flowfield?

Flowfield is a fluid sandbox: a living sheet of liquid light that fills your screen and never stops moving.

Stir it with a finger. Then pin things into it — jets that push forever, sinks that swallow, sources that pour, dye that stains the current, walls that bend it, warps that teleport it across the screen. Every fixture keeps working until you remove it. Build a machine of currents and watch it run.

First launch walks you through it: a guided tour introduces every tool one gesture at a time, each demonstrated by a ghost finger on the live fluid. Ninety seconds and the whole toy is yours.

Three moods to start from — Plasma, Water, Smoke — and a Tune panel that opens every dial behind them: viscosity, persistence, swirl, trail length, glow, particles into the tens of thousands. Find the setting that feels right and stay a while.

No goals. No timers. No ads. Nothing else to buy. A toy in the oldest sense: it does nothing except feel good to touch.
