Pin Screen

A pin screen that thinks in shapes: a field of rods rises in waves, sculpts the app icon in relief, then sinks away leaving the iPad standing, where the canvas assembles and a collaborator's comment makes the design and the field answer.

A dark lacquer tray holding a square field of matte rods that rise and sink in waves, raked by one warm bar light and a low hard key so every raised rod throws a crisp shadow into the void. Six beats over 30 s at 120 bpm: a top-down ripple, a grazing glide over a rolling swell, a slow orbit over a relief, the field sinking away, an extreme close-up, then a pull-back as the rods rise into a frame.

    THE IDEA. A pin screen that thinks in shapes. A square field of 20 × 20 matte black rods sits in a
    black lacquer tray under ONE raking bar light, so every millimetre a rod rises is drawn as a hard
    shadow. The rods push up in waves — a drop, a swell rolling at the lens — then sculpt the app's
    icon (an F on a rounded tile) in relief. The relief lets go, a slot opens in the middle and the
    whole field sinks away while the iPad stays put: it rises OUT of the field. Its canvas screen
    assembles in the air, a collaborator's comment types itself onto the selected canopy, the design
    answers (+40 mm), and the field answers with a ring. End: the rods hold a clean double-frame relief
    around the device, "Formwork" above the field.

    THE WORLD (1 unit = 1 mm, y up). Rods 29.5 × 29.5 mm on a 32 mm pitch (cols/rows 0–19, x/z =
    (i − 9.5)·32), 360 mm long, rest top at the field's local y 0. Tray: four 34 mm lacquer walls
    (inner edge ±322), a lacquer floor 500 mm down. The bar light: an 8 × 14 × 780 mm warm tube in a
    graphite housing lying along z at x −424, 40 mm above the rods, with a rect area light in it;
    the shadows come from a directional key on the same side at ≈ 24° elevation.
    The iPad never translates (a device `position` channel blanks screens): it stands at
    (0, −300, 0), anchor bottom, leaning back 12°. Scenes 1–3 have no iPad (the field is at y 0 over
    it); from s4 the field is a `g` whose `position` sinks 0 → −300, so the device is left standing.
    The rods are `repeat` blocks (400 instances); every rod's keys are `vary` expressions of its
    column / row, so each scene's rod choreography is a closed-form field, not 400 hand keys.

    BEATS AND SCENES (music 120 BPM: a beat = 0.5 s, a bar = 2 s; every cut on a bar line):
      s1-hook     0–4     HOOK. Straight down on the field: a drop at the centre (0.02) rings out as
                          a raised wave with its shadow; a second drop off-centre (2.2).
      s2-swell    4–8     Grazing low across the rod tops, the bar light a leading line on the left:
                          a travelling swell (sine, period 1.6 s) rolls toward the lens.
      s3-icon     8–12    High front ¾, slow orbit: the tile rises (+16), the outside sinks (−12),
                          the F pushes up through it (+54, easeOutBack) — the app icon in relief.
      s4-rise     12–20   FEATURE. The relief lets go, the slot over the device drops away, the field
                          sinks 300 mm (1.3–3.6): the iPad is left standing. Its canvas ASSEMBLES
                          (ui-assemble): paper, drawing, chrome, notes fly in, hover as a staircase
                          seen ¾ from the left, pack home magnetic while the lens swings to the front.
      s5-comment  20–26   PROOF. Mara's comment chip GROWS out of her pin (two edges pinned), the line
                          TYPES ("Raise the canopy 40 mm?"), ULTRA close-up along the chip (yaw −56…−60,
                          dof 40/12); Send; the canopy rises, columns grow (bottom pinned), H 3 200 →
                          3 240; a ring runs out through the field from the device.
      s6-end      26–30   END CARD. Pull back: the rods rise into a clean double-frame relief around
                          the iPad; "Formwork" (text3d) and "Design in 3D. Decide together." above
                          the far edge of the field, against the void.
