Monoliths

The picture is the shadow: five concrete masses around one phone under a single hard raking sun that swings between beats, giving every feature a different shadow composition on the same architecture.

Five bare concrete masses (a tower, wall, fin, block and pillar) stand around a low plinth under a dark sky, lit by a single hard raking sun that swings between beats so the same architecture throws new shadows, with a thin glowing slit between tower and wall. Five 6 s beats at 120 bpm over 30 s: a snap of sunlight and glide in, a high plan view and dive, a backlit close-up, a sundial crane, then a low slow push to land.

    THE IDEA. The picture is the shadow. Five raw concrete masses stand around a plinth that holds
    one phone, under ONE hard raking sun (a directional light with an authored shadow camera).
    The sun swings between beats, so every feature gets a completely different shadow composition
    on the same architecture, and the camera finds a new architectural angle each time. The copy is
    inlaid in the pavement; the name is cast into the face of a mass.

    THE WORLD. Pale board-marked concrete (bump only), a near-black sky, five masses
    (m1 tower 0.8 x 4.2 m back-left · m2 wall 2.4 x 2.6 m back-right, the end-card face ·
    m3 fin 0.18 x 3 m front-right · m4 block front-left · m5 pillar far back), a 560 x 960 plinth at
    the origin (top y 960; the phone stands on it, never translated), and one ACCENT back panel
    glowing in the gap between m1 and m2 with an ACCENT area light bouncing off it onto the plinth.

    BEATS (music 120 BPM: beat 0.5 s, bar 2 s — every cut on a bar line)

                      left and wheels up and round to back-left (0.35–4.6), the long shadows raking
                      across the floor to the plinth; the camera glides in from 6.4 m; the home screen
                      ASSEMBLES (ui-assemble: lyr-bg/content/nav/cta launch 1.9–2.8 from 9–10 m out

                      the new row lands

      s4-f3    18–24  near top-down plan; the sun sweeps from back-left to front-left and its shadow
                      edge uncovers caption 3; crane down to the phone: the hero bar fills, slot-cta
                      dips, a confirmation toast lands

                      the plinth left, the name rises on the face of m2, the tagline under it

    TEMPLATE SLOTS — what to change to re-skin this for ANY app (keep everything else constant):
      BRAND    text3d#e-name text= (app name) and text3d#e-tag text= (tagline), scene s5-end.
               Long names: keep size ≤ 300 and the anchor at x 700 so it stays on m2's face.
      ACCENT   ONE colour, three places: material m-accent (emissive panel), material m-name
               (the name), light#accent-back (in every scene's lights). Change the hex in all three.

               in scr-f2: keep the number + its label inside the card), slot-cta (press dip in f1 and
