What this is: a proof of concept for an arcade viewer / gallery — a 3D room for browsing a portfolio archive of completed games.
Every cabinet screen is a live iframe running a real build: walk the room, pick a game from the dropdown, and it loads on a cabinet with the right screen shape (9:16 phone games on the tall cabs, 16:9 on the wide ones) — playable in place.
Personal proof of concept.
