Fluid Ink Feedback

Pigment injected into a bounded feedback field, so the image carries the whole track's history.

Launch modes

Ink Bloom mode

Ink Bloom

Slow and viscous: pigment spreads outward and stays.

Dye Injection mode

Dye Injection

Many small injection points, each carrying its own colour.

Curl Swirl mode

Curl Swirl

The field rotates about its centre, so pigment traces spirals.

Filament Detail mode

Filament Detail

Treble stretches blobs into threads on one axis.

Dissipation Veil mode

Dissipation Veil

High dissipation: the field is always nearly clearing.

Marble Fold mode

Marble Fold

A shear folds the sheet back over itself, producing marbled bands.
