Structures that move, machines that live.

2D PBD testbench — the kernel behind Fig. 01.

Angulated scissor arch + crank-slider, from the S4 ring.

16 vertebrae, three tendons at 120° — full 3D kernel.

S1–S5 ring family choreography — a breathing body.

One shaft opens and closes five rings; the arm curls on three tendons.

Four bond maps under one contraction — Project II's structure engine.

The same four units extruded into fabric bands — orbit them in space.

One strip folds an upper and a lower structure — two zippers, one pull.

A graded catalogue, or a box pinched into two platforms — every band a real unit, packed or spread.

Twenty bands ring a tube — level, undulating, drifting, or pinched apart once around.

The mast stays round; how far each band reaches makes the plan a square — flat, undulating, or pinched.

Sixteen of those cylinders hung in a room, with a 1.70 m figure for scale.

Two, three, four or nine of those rings — apart, touching, stepped, interleaved at two heights, together or wave by wave.

One person crosses a room of 64 small units. The floor remembers; the units that read enough of it form — and stay formed.

Place people, drag them, or let them wander — the units form live, and two people together form twice as fast.
