Peaks — Cylinder
A drum bristling with quills: tapered spikes ring a cylinder wall and point outward while waves of blue, green and orange roll over the coat as it sways.
A cylinder wears a dense coat of quills, each one jutting straight out from the wall — a bottle-brush of soft, tapered spines. The body rocks gently on all three axes, and washes of blue, green and orange travel across the coat as it moves.
No quill is a mesh: each is about 150 single points stacked along the outward radial, thin at the far tip and fat at the base, so the round strokes fuse into a tapered tube on screen. The bases sit on a columns-by-rows lattice wrapped around the cylinder, and a Perlin field indexed by lattice position and stack depth picks every point's hue and brightness in a phase-shifted trig palette — the colour weather is that field made visible.
