Multiverse Art School — Bramblecrest: 12 students × 3 alternate creative paths visible simultaneously
A 3D MEGAVERSE demo: Bramblecrest Art School — 12 named students each exist in 3 SIMULTANEOUS alternate creative paths (painter / ceramicist / dancer). 3-way splitscreen scissor render every 38s. Cross-timeline echo at minute 5. Like Dead Poets Society meets Sliding Doors at art school.

## What this is
A 3D recreation of Bramblecrest Art School, a fictional cozy art school where every student exists in three simultaneous alternate creative paths visible at once. Twelve named students × 3 paths = 36 named students, plus 5 teachers, across five studios. Painting Studio is the easels + skylight-beam workspace. Ceramics Wheel is the four-wheel clay shelf room with three kilns. Dance Studio is the mirrored-wall barre + sprung-floor + piano. Sculpture Garden is the hedge-ring outdoor critique space with five plinths. Critique Room is the twelve-chair gallery with central pedestal and slide screen. The Timeline Fork Panel top-left shows the focused student's three paths (Path A · painter / Path B · ceramicist / Path C · dancer) with thesis % progress bars. Periodic 3-way splitscreen scissor render fires every thirty-eight seconds for ten seconds — the same student visible across all three paths simultaneously, with forkCamA/B/C cinematically catching the painter's brush, the ceramicist's wheel, and the dancer's pirouette. Cordelia Brookline (poet niece, manor mystery recurring cast) studies poetry across paths. Beatrix and Cassius Pemberton (twin prodigies — Mrs. Pemberton's grand-niece and grand-nephew, on the SS Meridian last summer) are full-tuition prodigies. Tobias Whitford-Cale (Lily Whitford's older cousin) is on a NEXLOGIC scholarship. Wren Halloran (Inspector Halloran's gracious daughter, crossword obsession) does evening pottery. Priya Auralis (descended from the Auralis Court). Nineteen director cameras cycle. AGENTIC THINK PANEL renders both STUDENT brain AND TEACHER brain panels side-by-side. CROSSOVER CHYRON reads five other demo localStorage keys (`bramblefield_school_v1`, `nexlogic_returns_v1`, `meridian_cruise_v1`, `thornpike_job_v1`, `auralis_court_v1`).
The school *remembers*. localStorage saves `art_school_paths_v1` (term, theses progress, echoes detected) AND writes to `recurring_cast_v1`. Each ten-minute reseed advances the term (Term I → II → III…).
You don't play it. You watch it. And it remembers across five other demos.
## Why this is mind-blowing
The chyron is the secret weapon: "Term II Week 7 — Cordelia's poem read into Auralis court record. Tobias paints a shape that echoes his path-C self's pirouette. Beatrix throws clay #14 of the senior thesis." That single line stitches three timelines AND three other demos in one beat — Cordelia on the Critique Room slide-screen close camera with her poem appearing on the slide (chyron pulls Auralis court line from `auralis_court_v1`, drama ladder rung 2 of 4 "thesis confirmed"), Tobias on the splitscreen scissor render with Path A painting a teardrop shape that matches Path C's pirouette arc (CROSS-TIMELINE ECHO fires — golden halo rings on both, "— CROSS-TIMELINE ECHO —" overlay, splitscreen forced on for 14 seconds, `memory.echoes` ticks +1), and Beatrix on the Ceramics Wheel close camera with clay #14 settling on the wheel (interaction sparkle as Cassius nods approval, twin prodigy bond +1 in `recurring_cast_v1`). The mid-cycle twist is the heart: the ECHO mechanism detects when a path-A student's painted shape (sampled as a 2D contour) matches a path-C self's choreography arc (sampled as a motion path). When the cross-correlation crosses a threshold, the multiverse leaks. Multiply that by 36 students each with a brain panel showing goal/need/have/plan/step/mood, a 3-way splitscreen scissor render firing periodically, a CROSSOVER CHYRON reading five other demos, RECURRING CAST that builds a cross-demo family tree (Tobias is Lily's cousin, Beatrix and Cassius are Mrs. Pemberton's grand-niece + grand-nephew, Wren is Halloran's daughter), and a Thesis-Exhibition-Week drama ladder, and you've got a Dead-Poets-Sliding-Doors stream that genuinely earns its multiverse scope. ALL FICTIONAL.
Prompt
Build a single-file HTML page that recreates "12 art school students each existing in 3 simultaneous alternate creative paths" as a continuous 3D autoplay world with MEGAVERSE crossover mechanics.
CONCEPT: BRAMBLECREST ART SCHOOL — fictional cozy art school. Dead-Poets-meets-Sliding-Doors tone.
Hard constraints:
- One HTML file, < 200KB.
- three.js r0.160.0 from unpkg, IIFE strict, reseed every ~10 min.
- First body line: <!-- ROUND19_MULTIVERSE v1 -->
- localStorage `art_school_paths_v1` (own) + writes recurring_cast_v1.
All R16+R17+R18 spec retained. R19 NEW:
1. TIMELINE FORK PANEL — focused student's 3 paths
2. 3-WAY SPLITSCREEN scissor render every 38s for 10s
3. CROSSOVER CHYRON — read 5 other demo localStorage keys
4. RECURRING CAST — Cordelia, Pemberton twins, Whitford-Cale (NEXLOGIC scholarship), Halloran's relative
5. DRAMA LADDER — Thesis Exhibition Week 1/3 + per-path progress
6. MID-CYCLE TWIST at 5min — cross-timeline echo (path-A painting matches path-C choreography)
Tone: COZY art-school. ALL FICTIONAL.
