Three lines of biro that light a room

A panel of six rotary dials, two rows of three, every pointer at a different position. Beside it, a card is taped up, written in biro: HALF AT TRAILERS, OUT ON CERT, UP ON END CARD.

Three lines. No panel, no button, no automation. Whoever's on the dials tonight reads the card and turns them by hand, at the right moment, from memory as much as from the paper.

The audience never sees the card. What they experience as the room simply getting dark, or slowly coming back, is three written instructions being followed in order.

Why does a lighting change need a written score at all?

Because the moments it happens at are exact, and exact moments aren't reliably held in memory across a whole shift.

HALF AT TRAILERS, OUT ON CERT, UP ON END CARD — three cues, three points in the evening, each one tied to something else on screen rather than to a clock. Writing them down turns a felt sense of timing into an instruction anyone on the dials that night can follow correctly, including somebody covering a shift who has never run this room before.

What does OUT ON CERT actually mean?

That the lights go fully out when the certificate card appears, using the card as the trigger rather than a stated time.

A certification card is shown before the trailers finish and the auditorium is expected to be dark for it. The instruction doesn't say "at 7:41" — it says which image on screen the room should already be responding to, because the card and the light change are meant to land together, not one after the other.

Why are all six dials set to different positions?

Because six lights rarely share one job, and a single lever would flatten six decisions into one.

Aisle lights, wall washes, the stage-adjacent glow, the exit-side wash — each has its own dial because each needs its own level at rest, independent of the others. What's printed is a setting somebody arrived at over time and left, not a factory default: six small, separate judgements about how dark is dark enough.

Can a shirt reproduce a real venue's actual lighting cues?

The three-line format and the craft of cueing are nobody's property. A specific venue's exact wording, if it were traceable to one building, would be closer to that venue's own procedure than to a general one.

Nothing about HALF AT TRAILERS or OUT ON CERT identifies a place — the phrasing describes a near-universal sequence in any auditorium running trailers before a certificate card and a feature. Writing a card in a hand that could belong to anyone, in a booth that could belong to anywhere, is both the safer version and the one that actually generalises.

Does the same handwritten-correction idea show up elsewhere in the building?

Yes — the running order in the booth carries its own pen mark, made after the typed sheet was already in use. The lighting card and the running order are the same kind of object: something printed or planned in advance, corrected by whoever actually runs the room, because the room often needs a small adjustment the plan didn't anticipate.

Does the timing connect to anything else in the booth?

It sits right next to the tightest timing in the building: the four-second window in which one projector hands off to another. The lighting cues are looser by comparison, but they're read off the same screen, by the same person, often between two much more exacting jobs happening seconds apart.

Isn't three lines of biro too small a thing to build a design around?

It's small because the instructions themselves are small — three cues is the entire content of the job, and inflating it would misrepresent what the card actually says.

The panel of six dials gives the design its scale and its geometry; the card supplies the only text. Together they're closer in spirit to a chalked running total kept on a workshop wall than to a poster — a working note, not a statement.

Does it print well?

Yes — six circles with pointers and three lines of handwriting are both flat, hard-edged shapes that hold up well at fabric scale.

The dial pointers should stay crisp and geometric; the card's handwriting can be looser, since biro on masking tape was never meant to be neat. Keep the two elements in different inks so the eye reads "panel" and "note" as separate objects, the way they are on the wall.

Ink blue or charcoal grounds suit it; two inks, dials in a pale metallic-reading tone and the card in a warm off-white.

How do I get one made?

Describe the panel at JustOG — how many dials, what the three cues say, and how the card is fixed up. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped.

Designs other people have published are in the shop.

Nobody in the seats claps for the lights; they just notice, briefly, that the room changed.
