Transcendental Bessel–Fourier loom · recursive parametric geometry
A single closed thread is traced through a radius built from a Bessel function driven by a Fourier modulation. Each petal is a place where the Bessel term swings through a lobe while the Fourier term reinforces it; the crossings are not drawn, they are where the same thread returns. The same mathematics governs FM synthesis sidebands, vibrating circular drumheads and diffraction rings.
