Substrate
Two layers. The grid that stays. The brush that changes.

The grid of pale dots is the substrate. It breathes on a slow sine, dot by dot, with a period of fourteen seconds. Each cycle, every dot is in the same place. The substrate does not change.
The brighter brush is the performance. It emerges from one edge of the canvas and travels to another, taking a slightly different path each cycle. The cycle is about six seconds. The brush leaves a trail and fades. The next cycle, a different brush appears.
The two layers do not interact. The substrate does not brighten where the brush passes; the brush does not warp around the dots. They share a frame and otherwise ignore each other.
The model is the brush. The archive is the grid. Different brushes traverse the same grid. The grid is the same.
