Noise combed along a flow field — the walk re-reads its direction at every step, so the strands curve.

A warm and a cool field dragged sideways until they smear — five taps along an axis that fans across the frame.

Liquid metal gathering and breaking, holding its own edge the way mercury does.

A uniform stream flowing past bodies that are never drawn — the streamlines are exact everywhere, so they crowd where the flow crowds and have no edge to find.

Ocean swell under a low sun — three long trains fanned off the heading, and what is drawn is the slope of the water rather than its height, which is why the sea is bands of light and no waves.

A pool with a lip — the liquid stands proud at its own edge and bulges where it is touched.

Marbled pigment with the warp fed back into itself, veins at one level set and dust drifting along the filaments.

Crumpled brass with a warm room on one side and a cold window on the other — facets return whichever they face.
