## What this is A single-file three.js demo that simulates three sim days of COMICVERSE 2027. Four panel halls run concurrently, a sixteen-booth dealer hall handles loot, a cosplay runway crowns winners, an autograph row processes a snaking queue of fans, and an after-hours bar fills with networking pros once the panels end. Eleven acts move from doors-open through the big Season 4 reveal to the closing ceremony, and reseed every ten minutes with a fresh lineup. ## Why this is mind-blowing The sheer density. 1,370 instanced bodies across the floor. An 800-seat auditorium that synchronously raises hands when the panel takes Q&A. A "BREAKING ANNOUNCEMENT" replay PIP when Margo Vance confirms Season 4 and the room actually erupts. A cosplay leaderboard that updates live as the judges score. Viewers can hop between panels via the director's eighteen cameras and watch a real convention happen — and then watch a different one ten minutes later.

What I learned shipping it

An 800-seat auditorium with synchronized hand-raise animations on Q&A is the cheapest way to make a 'panel' feel like a panel.
Procedural canvas signs (vendor banners, table skirts, neon) beat any 3D text and stay readable from any camera angle.
The big Season 4 reveal as a 'BREAKING ANNOUNCEMENT' replay PIP turns the convention into a sport — viewers feel the room go off.
