The slide that broke open

A flat corporate slide cracks open into depth: the pane becomes a floor, a phone and a room, the room becomes one tile of a lattice of worlds, and it all shrinks back to one flat rectangle.

A dark glass pane standing on a mirror floor, then a cut-away designer studio at dusk, then a seven-by-seven lattice of glass tiles each holding a miniature world; it starts flat and ends flat. Seven beats over 61 s at 120 bpm, each freezing on its last frame until advanced: a dead-square open, a dolly-zoom and widening orbit, depth peeling out, a dive, a powers-of-ten pull, then top-down and flat.

    THE SLIDE THAT BROKE OPEN — a 7-slide presentation reel for Strata (fictional), the presentation app
    that builds decks with real depth. Each scene is one slide; each freezes on its last frame
    (metadata › pauses › pause at duration − 0.04) until the presenter presses Space.

    THE TRICK: it starts as an ordinary flat corporate slide — filmed 25.7 m away on a 4° lens, dead square,
    no post — then the camera moves and the slide is a pane of glass in a void; its lines peel off into depth,
    the pane falls over and becomes the floor of a world, the camera goes deeper (a phone, a room, a laptop)
    and then bigger (the room is one tile of a 7 x 7 lattice of worlds), and the whole thing shrinks back
    into one flat 16:9 rectangle: the end card. Flat at the start, flat at the end.

    WORLDS (1 unit = 1 mm)
      A · the slide (origin): a 3190 x 1790 x 24 dark-glass pane standing on an endless black mirror floor.
          Its face = a white backer plane + five free-standing ui3d strips (HTML → html2ui, x10 into the
          world: title band, three bullets, footer). Tips back about its back-bottom edge onto the floor
          (top y = 24). On it: five coral towers, a plinth with the iPhone, a field of 6000 points.
      B · the room (x = +40 000): a cut-away designer's studio at dusk, 4.4 x 3.2 m, no ceiling / front wall.
          Props (TRELLIS, scale = longest side): desk lamp 480 · chair 900 · fiddle-leaf fig 1300 · mug 110 ·
          books 240 · stone sculpture 220 · headphones 200 · vase 300 · sideboard 1300. Desk, shell, rug,
          window = primitives. Key = the lamp; a dusk window; the screen; the neon headline on the wall.
      C · the lattice: the room's floor is the centre tile (6400 x 3600) of 7 x 7 glass tiles on a
          7200 x 4050 pitch — 50.4 x 28.35 m, 16:9 overall — each tile a miniature world of light.

    SLIDES  (s1 6 · s2 9 · s3 9 · s4 9 · s5 10 · s6 9 · s7 9 = 61 s, hard cuts on matching frames)
      1 s1-flat    FLAT — the boring slide; bullets click on 1.0 / 2.2 / 3.4. No lens, by design.
      2 s2-crack   THE CRACK — dolly-zoom 4° → 32° with a growing orbit; strips lift to 300–960 mm;
                   white sinks away; lens comes on. "What if your slides had depth?"
      3 s3-fall    THE FALL — the pane tips onto the floor; bullets fly past the lens and land as
                   towers / a phone on a plinth / a field of points. "Bullets, made real."
      4 s4-phone   DEEPER — the Strata viewer assembles on the iPhone. "Present from anywhere."
      5 s5-build   DEEPER — dive into the phone's preview, match cut to the laptop's canvas, the AI prompt
                   types and grows (the ONE ultra close-up), the canvas re-renders. Neon "Build in depth."
      6 s6-bigger  BIGGER — powers-of-ten pull: room → tile → lattice. "Every idea, its own world."
      7 s7-return  THE RETURN — top-down, the lattice shrinks to a rectangle, the end card lands on it and
                   the lens narrows 30° → 4° until it fills the frame, flat: "Slides with depth."

    SOUND: an original 120 BPM bed (music/, procedural-music; a stock C-major piano loop for the boring slide
      that tape-drops into A minor on the crack) phrased per slide, plus designed SFX (media/sbo-*.wav) and
      engine UI sounds; every sound starts inside its own slide so nothing plays across a pause.
    ENGINE NOTES (worked around here): a mirror floor reflects the HDR's softboxes as a white wedge, so
      World A runs without an environment; with two devices carrying overlay stages in one scene the second
      device drew only its camera-framed card, so s5's phone screen is a free-standing ui3d on its glass;
      a camera-framed overlay card paints over its overlapping siblings, so the re-rendered canvas and the
      "Building" pill live INSIDE the framed lp-canvas card; overlay
