Shelfwise

A spiral tower of books lights up as a search types; one book slides out, opens on an iPad where page one types itself, and the tower collapses into the logo ring.

A round library tower at night, its spiral of cloth-bound books in walnut and brass lighting in a wave, with warm lamps and drifting dust; one book slides from the wall and opens onto a marbled endpaper as warm light spills out. Six quick beats of about 2.3 s over 15.6 s at about 123 bpm: a rise from the floor, a slide and swing, a hinge open, a hold, a pull back, then the spiral winding into a ring to land.

    THE IDEA — The Endless Shelf. Shelfwise is a reading and audiobook app. You ask for a mood, the
    library answers: a tower of forty thousand books lights in a spiral, one book slides out to
    meet you, it opens into an iPad, the first paragraph writes itself, the title lifts off the
    page, the hours you listened climb, and the tower's spiral winds itself into the Shelfwise ring.

    THE STAGE — one round tower of books at night, axis at the origin, floor at y 0. Twelve walnut
    shelf rings (flattened tori) every 340 mm; on each, 72 cloth spines on a circle (5° apart, the
    odd rows offset 2.5°), placed with sin/cos by one repeat: spine faces at r 700, books 150 deep.
    Brass globes hang under shelves 2/5/8/11; a lamp shaft falls down the axis through the dust.
    The hero book (row 4, slot 36: 180°, its spine at z −700, centre y 1525) is a rig of its own
    (template#hero-book) whose cover hinges on a group; the iPad sits inside it like a folio.
    S6 leaves the tower for a dark void where the tower's spiral is drawn in 432 gold points.

    CHAPTERS (scene · local seconds; gap-clock=run, a scene's clock starts with its incoming gap)
      s1-tower  2.6  HOOK    looking up the tower; the camera spirals up the inner wall while the
                             gilt bands light in a spiral wave; the glass bar fades in and
                             "cosy mystery, rainy night" types (1.0 → 1.95); Go lights (2.3) and one
                             spine behind the bar flares. zoom-through.
      s2-pick   2.0  PICK    on that spine: the book slides out of the wall (0.35 → 0.85) and swings
                             to face the lens (→ 1.55), the slot glowing behind it. blur-dissolve.
      s3-open   1.8  OPEN    the cover hinges open (0.3 → 1.1): an iPad lies where page one should
                             be, warm light spills out; the lens squares up on the screen. zoom-through.
      s4-read   2.4  READ    the first paragraph types itself line by line (0.3 → 1.9); Listen is
                             pressed (2.05), the player runs. blur-dissolve.
      s5-proof  2.4  PROOF   pull back: "The Night" rises and "Library" pops off the page in gilt;
                             LISTENED THIS MONTH climbs 0h 00m → 12h 40m. light-leak.
      s6-mark   3.4  CTA     the tower's spiral as 432 gold points winds into a dotted torus, the
                             torus collapses into the brass ring, the open-book glyph pops inside,
