EXP 04Turing Roomfive friends, one language model

One of us is typing.

Six seats in a chat room. Five are your friends. One is a language model doing its level best to blend in. Answer three questions, argue about the answers, then vote — and hope you picked right.

The setStudio 41, Tuesday at nine, 1961
The Turing Room title card: cream card stock, condensed gothic lettering, on a dark studio ground.
The title card on the easel. Every surface is printed card or painted flat — nothing glows, because in 1961 nothing did.
The studio floor on a wide screen: plate rail with ON AIR panel and clock, a tilted cream question card and numbered seat cards stage-left, the transcript running full height stage-right.
The chat is the studio stenographer’s transcript — ruled gutter, monospace speaker column, timestamps, and never a speech bubble. That one anachronism would kill the whole thing.
On a phone: the plate rail, a tilted cream question card, and five numbered seat cards.
One hero element per screen. Here it is the question card — tilted, on card stock, in a Clarendon-family slab.
The sign-in slate: a dark chalkboard listing numbered panelists who have signed in.
The green room. What’s My Line? swapped its white sign-in pad for a black slate in 1950 because the studio lights blew out the signatures on camera — so ours is slate, and pure white appears nowhere in the product.
The reveal: numbered cards face-up on the panel desk, four reading “a human being” and one reading “the ringer”, with the tally and an unlit APPLAUSE panel.
“Will the real human being please stand up?” Two feints with lengthening beats, then one card turns and stops dead. There is no drumroll — the period bed under a reveal is silence.

The research picks the palette, not taste

Every colour traces to a documented source: the one attested Goodson-Todman house accent (blue and gold, by their designer Ted Cooper), the Rosco broadcast reflectance standard, and the cream card stock the production department actually printed on. Pure white is the single biggest anachronism available — and it was corrected on air in 1950 for exactly that reason.

Nothing flashes, and a build gate enforces it

A blinking APPLAUSE sign is the thing everyone remembers — and the surviving 1950s unit has no flasher hardware in it. It is also the most dangerous animation a screen can carry. The sign lights once and holds; card cascades run at 1.4 Hz against a 3 Hz legal limit; and a lint fails the build on any repeating animation, targeting the mechanism rather than a colour name.

The AI is never called the AI

In the fiction it is the ringer, the panel is the panel, and the room code is a studio number. The word that breaks the world never appears in the interface.

The bot’s tells are statistical, not scripted

Response timing is drawn from log-normal distributions with one typing speed rolled per game — because uniform delay is the single most reliable machine signature in the detection literature, and a bot that re-rolls its speed per message is a tell of a different kind.

Under itthe build

Rooms are Cloudflare Durable Objects — one object per studio, holding the whole game in memory and driving its phases off a single alarm. The client is hand-written HTML, CSS and JavaScript with no build step, and every sound in the product is synthesised at runtime through one master bus that sums to mono and band-limits to roughly 180 Hz–6.5 kHz — a 1961 television speaker. There are no audio files.

The hidden player runs on Claude Haiku with a behavioural signature rolled fresh each game, so regulars can never learn its habits. Its difficulty tunes itself: every finished game updates a Beta posterior per persona, and the next game is drawn by Thompson sampling toward a target catch-rate — the game teaching itself how hard to be, from how often tables actually catch it.
