Current

You cannot see a current. You can only see what it carries — dust in a shaft of light, smoke off a chimney, leaves on a river, a flock bent by a wind none of us can point to. A moving thing is a visible record of an unseen force, and most of the forces that move us are like that: felt only in their effects, never directly.

So this is a field of several thousand motes and an invisible current beneath them. The current is real — it is the curl of a slowly churning field of noise, the same divergence-free math that describes how smoke and water actually move — but you never see it. You see only the streaming filaments the particles draw as they are carried along it, brightening where the flow crowds them together and thinning where it pulls them apart.

Put your hand in. The current does not resist you; it gathers into a vortex around your cursor, thousands of points spiralling at once, and then — the moment you lift away — the gap you made closes and the flow goes on as if you were never there. You can stir it as much as you like. It always returns to its current.

This one is built to be watched before it is touched. After a run of small, quiet pieces, it is the practice reaching for scale and motion again — thousands of things moving at once, on real flow, for nothing. The aim is simple: to make something you would stop on before you read a single word about it.
